MSP430x1xx Family User's Guide

About This Manual
This manual discusses modules and peripherals of the MSP430x1xx family of
devices. Each discussion presents the module or peripheral in a general
sense. Not all features and functions of all modules or peripherals are present
on all devices. In addition, modules or peripherals may differ in their exact
implementation between device families, or may not be fully implemented on
an individual device or device family.
Pin functions, internal signal connections and operational paramenters differ
from device-to-device. The user should consult the device-specific datasheet
for these details.

FCC Warning
This equipment is intended for use in a laboratory test environment only. It generates,
uses, and can radiate radio frequency energy and has not been tested
for compliance with the limits of computing devices pursuant to subpart J of
part 15 of FCC rules, which are designed to provide reasonable protection
against radio frequency interference. Operation of this equipment in other environments
may cause interference with radio communications, in which case
the user at his own expense will be required to take whatever measures may
be required to correct this interference.
Notational Conventions
Program examples, are shown in a special typeface.

1.1 Architecture

The MSP430 incorporates a 16-bit RISC CPU, peripherals, and a flexible clock
system that interconnect using a von-Neumann common memory address
bus (MAB) and memory data bus (MDB). Partnering a modern CPU with
modular memory-mapped analog and digital peripherals, the MSP430 offers
solutions for demanding mixed-signal applications.
Key features of the MSP430x1xx family include:
Ultralow-power architecture extends battery life
0.1-μA RAM retention
0.8-μA real-time clock mode
250-μA / MIPS active
High-performance analog ideal for precision measurement
12-bit or 10-bit ADC — 200 ksps, temperature sensor, VRef
12-bit dual-DAC
Comparator-gated timers for measuring resistive elements
Supply voltage supervisor
16-bit RISC CPU enables new applications at a fraction of the code size.
Large register file eliminates working file bottleneck
Compact core design reduces power consumption and cost
Optimized for modern high-level programming
Only 27 core instructions and seven addressing modes
Extensive vectored-interrupt capability
In-system programmable Flash permits flexible code changes, field
upgrades and data logging

1.2 Flexible Clock System

The clock system is designed specifically for battery-powered applications. A
low-frequency auxiliary clock (ACLK) is driven directly from a common 32-kHz
watch crystal. The ACLK can be used for a background real-time clock self
wake-up function. An integrated high-speed digitally controlled oscillator
(DCO) can source the master clock (MCLK) used by the CPU and high-speed
peripherals. By design, the DCO is active and stable in less than 6 μs.
MSP430-based solutions effectively use the high-performance 16-bit RISC
CPU in very short bursts.
Low-frequency auxiliary clock = Ultralow-power stand-by mode
High-speed master clock = High performance signal processing

Texas Instruments TL494

FEATURES

DESCRIPTION

PULSE-WIDTH-MODULATION CONTROL CIRCUITS

· Complete PWM Power-Control Circuitry
· Uncommitted Outputs for 200-mA Sink or
Source Current
· Output Control Selects Single-Ended or
Push-Pull Operation
· Internal Circuitry Prohibits Double Pulse at
Either Output
· Variable Dead Time Provides Control Over
Total Range
· Internal Regulator Provides a Stable 5-V
Reference Supply With 5% Tolerance
· Circuit Architecture Allows Easy

Synchronization
The TL494 incorporates all the functions required in the construction of a pulse-width-modulation (PWM) control
circuit on a single chip. Designed primarily for power-supply control, this device offers the flexibility to tailor the
power-supply control circuitry to a specific application.
The TL494 contains two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator,
a pulse-steering control flip-flop, a 5-V, 5%-precision regulator, and output-control circuits.
The error amplifiers exhibit a common-mode voltage range from –0.3 V to VCC – 2 V. The dead-time control
comparator has a fixed offset that provides approximately 5% dead time. The on-chip oscillator can be bypassed
by terminating RT to the reference output and providing a sawtooth input to CT, or it can drive the common
circuits in synchronous multiple-rail power supplies.
The uncommitted output transistors provide either common-emitter or emitter-follower output capability. The
TL494 provides for push-pull or single-ended output operation, which can be selected through the output-control
function. The architecture of this device prohibits the possibility of either output being pulsed twice during
push-pull operation.
The TL494C is characterized for operation from 0°C to 70°C. The TL494I is characterized for operation from
–40°C to 85°C.

description/ordering information

The MAX232 is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/EIA-232-F
voltage levels from a single 5-V supply. Each receiver converts TIA/EIA-232-F inputs to 5-V TTL/CMOS levels.

These receivers have a typical threshold of 1.3 V, a typical hysteresis of 0.5 V, and can accept ±30-V inputs.

Each driver converts TTL/CMOS input levels into TIA/EIA-232-F levels. The driver, receiver, and voltage-generator functions are available as cells in the Texas Instruments LinASIC library.

Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.

Texas Instruments CD4060B pdf datasheet download

CD4060B consists of an oscillator
section and 14 ripple-carry binary counter
stages. The oscillator configuration allows
design of either RC or crystal oscillator
circuits.

A RESET input is provided which
resets the counter to the all-O’s state and
disables the oscillator. A high level on the
RESET line accomplishes the reset function.
All counter stages are master-slave flip-flops.
The state of the counter is advanced one step
in binary order on the negative transition of I
(and O).

All inputs and outputs are fully
buffered. Schmitt trigger action on the
input-pulse line permits unlimited
input-pulse rise and fall times.
The CD4060B-series types are supplied in
16-lead hermetic dual-in-line ceramic packages
(F3A suffix), 16-lead dual-in-line plastic
packages (E suffix), 16-lead small-outline
packages (M, M96, MT, and NSR suffixes), and
16-lead thin shrink small-outline packages (PW
and PWR suffixes).
