Product details

Serial interface set and peripheral mix

On-chip connectivity includes I²C, SPI, UART/USART, IrDA, and LINbus — enough to talk to most common sensors, displays, and LIN slave nodes without external glue logic. The peripheral set adds a brown-out detect/reset, PWM outputs, and a watchdog timer, covering the basic control and supervision needs of a small embedded system.

Memory sizing — what fits in 8 KB Flash and 512 B RAM

With 8 KB of Flash, the firmware budget is tight for a full RTOS or a large protocol stack; this part is aimed at bare-metal control loops, simple state machines, and sensor polling routines. The 512-byte RAM limits data buffering.

Frequently asked questions

What is the closest pin-compatible alternative to MSP430G2403IPW20R?

The MSP430G2xx family includes several pin-compatible Flash and RAM density options in the same 20-TSSOP package, such as the MSP430G2452 (with more Flash/RAM) — a cross-reference should be validated against firmware size and RAM budget.

What is MSP430G2403IPW20R's listed speed?

The CPU core runs at 16 MHz.
