The on-chip LCD driver handles the display directly, and the 512 KB Flash plus 32 KB RAM leave room for the metering algorithms, tamper detection, and a communication stack (I²C, SPI, UART/USART, LINbus). ## 100-LQFP — standard fine-pitch QFP for inspection The 100-LQFP (14x14 mm body, 0.5 mm pitch) is a widely used package for metering boards. It is hand-solderable for prototypes, reflow-friendly for production, and the exposed leads make X-ray and AOI inspection straightforward.","metaTitle":"Texas Instruments MSP430F67791AIPZ 16-bit MCU, 25MHz","metaDescription":"TI MSP430F67791AIPZ 16-bit metering SoC with 25MHz CPUXV2 core, 512KB Flash, 32KB RAM, 7x24b sigma-delta ADC, LCD driver.
