DESCRIPTION The Texas Instruments MSP430™ family of ultra-low-power microcontrollers consists of several devices featuring different sets of peripherals targeted for various applications. The architecture, combined with five low-power modes, is optimized to achieve extended battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows the device to wake up from low-power modes to active mode in less than 6 µs. FEATURES • Low Supply Voltage Range: 1.8 V to 3.6 V • Ultra-Low-Power Consumption: – Active Mode: 200 µA at 1 MHz, 2.2 V – Standby Mode: 0.7 µA – Off Mode (RAM Retention): 0.1 µA • Five Power-Saving Modes • Wake Up From Standby Mode in Less Than 6 µs • Frequency-Locked Loop, FLL+ • 16-Bit RISC Architecture, 125-ns Instruction Cycle Time • Scan Interface for Background Water, Heat, and Gas Volume Measurement • 16-Bit Timer_A With Three Capture/Compare Registers • 16-Bit Timer_A With Five Capture/Compare Registers • Integrated LCD Driver for Up to 96 Segments • On-Chip Comparator • Serial Onboard Programming, No External Programming Voltage Needed Programmable Code Protection by Security Fuse • Brownout Detector • Supply Voltage Supervisor and Monitor With Programmable Level Detection • Bootstrap Loader (BSL) in Flash Devices • Family Members Include: – MSP430FW423 8KB + 256B Flash Memory, 256B RAM – MSP430FW425 16KB + 256B Flash Memory, 512B RAM – MSP430FW427 32KB + 256B Flash Memory, 1KB RAM – MSP430FW428 48KB + 256B Flash Memory, 2KB RAM – MSP430FW429 60KB + 256B Flash Memory, 2KB RAM • Available in 64-Pin Quad Flat Pack (QFP) • For Complete Module Descriptions, See the MSP430x4xx Family User"s Guide, Literature Number SLAU056 APPLICATIONS • Analog Sensor Systems • Digital Sensor Systems • Gas, Heat, or Water Meters • Industrial Meters • Hand-Held Meters
