MSP430FG437IPN

The Texas Instruments MSP430FG437IPN is a low-power, 16-bit microcontroller based on a RISC architecture, operating at speeds up to 8 MHz. It offers 32KB of Flash program memory and 1KB of SRAM.

Key electrical features include a wide supply voltage range of 1.8 V to 3.6 V and ultra-low power consumption in various modes. The device integrates a 12-bit analog-to-digital converter (ADC) with internal reference and sample-and-hold, along with dual 12-bit digital-to-analog converters (DACs) with synchronization. It also includes a single-channel DMA controller, three configurable operational amplifiers, and an on-chip comparator.

For connectivity, the MSP430FG437IPN supports serial communication interfaces like SPI and asynchronous UART/USART. It features timers such as Timer_A and Timer_B, a brownout detector, and a supply-voltage supervisor. The microcontroller is designed for applications requiring an integrated segment liquid crystal display (LCD) driver for up to 128 segments.

Packaged in an 80-pin LQFP, the MSP430FG437IPN is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C. The device also includes a bootloader (BSL) for serial onboard programming without external voltage, and programmable code protection.
