Low-power 16 bit OTP microcontrollers

26 Jan 2000 DSP, Micros & Memory

The MSP430P325A and the MSP430P337A, the newest members in the MSP430 microcontroller family from Texas Instruments, are claimed to offer an unmatched ratio between ultra-low power consumption and a high-performance, 16 bit microcontroller core in a one-time-programmable (OTP) version.

The devices reduce current consumption by more than 80%, compared to existing MSP430 OTP devices and are now comparable with the ROM versions. The 16 bit RISC core is built in an orthogonal structure and uses only 27 core instructions which makes it easy to use.

The MSP430P325A features include a high-resolution, 14 bit analog-to-digital converter (ADC) and an integrated LCD driver for up to 84 segments, making the device complete measurement system on a single chip. The device is ideally suited for portable measurement equipment in which the ultra-low power consumption combined with the 14-bit ADC and LCD driver help to save system cost.

The MSP430P337A offers device features such as an integrated hardware multiplier, universal synchronous/asynchronous receiver/transmitter (USART) and a LCD driver for up to 120 segments. The device supports higher-end applications in which arithmetic-intensive calculations can benefit from the integrated hardware multiplier and the USART for ease of communication off-chip.

Features

* Ultra-low power OTP cell included.

* Ultra-low power consumption: 500 µA active, 1,3 µA in standby, 0,1 µA in RAM retention/off mode.

* 16 bit orthogonal RISC architecture with high throughput and up to 3,3 MIPS.

* Fast wake-up from sleep mode (max 6 µs).

* Seven different addressing modes for 51 (27 core) instructions.
