Product details

At 16 MHz the core executes most instructions in one or two cycles.

4 KB Flash and 256 bytes RAM — sizing the firmware envelope

4 KB of Flash is a tight envelope. The 256-byte RAM is the real constraint: keep the stack shallow, avoid large local arrays, and use the Flash for constant tables.

Lifecycle — EOL hot, sourced through independent channels

The MSP430G2353IN20 is flagged as end-of-life hot. That means TI has issued a last-time-buy notice; the part is no longer in volume production through franchised distribution. For new BOM lines or long-life products, this is a red flag — plan for a one-time buy or a pin-compatible migration.

Through-hole 20-DIP — board fit and rework

The 20-pin DIP package (0.300-inch row spacing, 7.62 mm pitch) is a standard through-hole footprint. It mates with a 20-pin DIP socket or solders directly into plated through-holes.

Frequently asked questions

Is MSP430G2353IN20 obsolete?

Yes, the MSP430G2353IN20 is end-of-life (EOL hot). It is no longer in volume production through franchised distribution. The part is available through independent surplus and broker channels, sourced to order against an RFQ.

What is the difference between MSP430G2353IN20 and MSP430G2452?

The MSP430G2452 has 8 KB Flash and 512 bytes RAM, double the memory of the MSP430G2353IN20, but shares the same 20-pin DIP package, core, and peripheral set. If the firmware needs more than 4 KB of code or 256 bytes of RAM, the MSP430G2452 is a direct pin-compatible upgrade.

What is MSP430G2353IN20's listed speed?

The MSP430G2353IN20 is rated for a 16 MHz core clock. At 16 MHz the CPU16 core delivers roughly 8–16 MIPS depending on the instruction mix.
