Product details

Memory budget — 120 KB Flash, 4 KB RAM

120 KB of Flash gives room for a moderate firmware stack — a Modbus RTU library, a segmented LCD driver, and a PID control loop fit without squeezing. The 4 KB RAM is tight for buffering; designs that log data or run a TCP/IP stack will need external SRAM or a part with more on-chip RAM. The 256-byte information memory (part of the Flash block) is useful for calibration constants that survive firmware updates.

Industrial temperature range — deployment context

The 113-ball BGA Microstar Junior (7x7 mm) demands a controlled solder profile and X-ray inspection post-reflow — not a hand-solder part for prototype boards.

Texas Instruments has marked the MSP430FG4619IZQW as obsolete. No official successor order code is listed in the product change notice. No direct factory last-time-buy window remains open.

Frequently asked questions

What is the replacement for MSP430FG4619IZQW?
