FRAM-based MSP430: what the 16 KB unified memory means
The headline feature is its 16 KB FRAM program memory — a non-volatile memory that behaves like Flash for code storage but writes at SRAM-like speeds, with no erase-before-write penalty. This means you can treat the FRAM as both program store and data-logging space without worrying about wear-leveling or sector erase times. The part also carries 1K x 8 of SRAM for stack and variables.
Package and mounting — 38-TSSOP
Housed in a 38-pin TSSOP with 0.240" body width and 0.65 mm pitch, surface-mount only. The supplier device package is 38-TSSOP. No exposed pad — thermal dissipation is through the leads, so keep the copper pours generous if running the ADC or PWM at high duty cycles near the top of the temperature range.
This part is current-production and available through independent distribution.
