The 20 MHz clock is the nominal operating frequency. That is enough throughput for a 16-bit PID loop running at a few kilohertz or for polling a dozen I²C sensors in a round-robin schedule. ## Memory sizing for the firmware budget 256 KB of Flash and 18 KB of RAM is a comfortable allocation for a mid-complexity embedded application. The Flash can hold a USB stack, a FAT file system, and several hundred lines of application code. The 18 KB RAM is the tighter constraint: if your data buffer or display frame buffer exceeds that, you will need to page data to Flash or pick a part with more SRAM. The 74 general-purpose I/O lines give you room for a parallel LCD, keypad matrix, and a handful of status LEDs without multiplexing. Texas Instruments has marked the MSP430F5632IZQWR as obsolete. There is no official TI replacement listed in the current evidence, so a pin-compatible drop-in is not guaranteed.","metaTitle":"TI MSP430F5632IZQWR 16-bit MCU, 20MHz, 256KB Flash, 113-BGA","metaDescription":"MSP430F5632IZQWR 16-bit MCU from TI MSP430F5xx series. 20MHz core, 256KB Flash, 18KB RAM, USB + serial interfaces.
