FRAM-based MSP430 — what sets this part apart
The MSP430FR2033IG56R: It runs at 16 MHz and integrates 15.5 KB of FRAM program memory — a non-volatile storage that writes at near-SRAM speed with essentially unlimited endurance, unlike Flash. The 2K x 8 RAM and 52 general-purpose I/O lines suit it for metering, sensing, and control panels where low power and frequent data logging are the norm. An internal oscillator keeps the BOM lean, while the 8-channel 10-bit ADC handles analog inputs without an external converter.
Supply voltage and temperature — design-in constraints
The 56-TSSOP package has a 0.240" body width and 6.10 mm body length.
Peripherals and connectivity — what is on-chip
On-chip peripherals include a brown-out detect/reset, power-on reset, PWM, and watchdog timer — the usual set for a standalone controller that must survive power glitches. For serial communication there are I²C, SPI, UART/USART, plus IrDA and SCI. The 52 I/O pins are more than enough for a keypad-and-LCD user interface or a sensor array with parallel data buses.
Lifecycle — active and available
There is no NRND flag, no last-time-buy notice, and no EOL announcement on this base number.
