Product details

25 MHz core speed — enough for CAN-bridge duty

The 25 MHz ARM Cortex-M3 core delivers around 1.25 DMIPS/MHz, which translates to about 31 DMIPS. That is sufficient for a CANopen node handling a few hundred PDOs per second, a UART-to-CAN gateway, or a simple PID loop for a brushed DC motor. It will not run a TCP/IP stack with heavy encryption, but for deterministic field-level control the speed is well matched to the 64 KB Flash budget.

Memory sizing: 64 KB Flash, 16 KB SRAM

The 64 KB Flash (64K x 8) and 16 KB SRAM (16K x 8) define the firmware envelope. A typical CANopen bootloader plus application stack fits in about 32 KB, leaving headroom for a calibration table or a second protocol. The 16 KB SRAM is tight for a large frame buffer or a multi-channel data logger, but adequate for a command-response protocol with a handful of 8-byte CAN messages in a double-buffer scheme.

NRND — plan for a last-time buy or a migration

For a running BOM line, this is the moment to secure a last-time-buy quantity or qualify a pin-compatible successor.

Frequently asked questions

Is the LM3S2110-IQC25-A2T obsolete or NRND?

It is still available for existing production but not intended for new design starts. Plan a last-time buy or a migration to a TM4C12x series part.

What is the replacement for the LM3S2110-IQC25-A2T?

There is no exact pin-compatible replacement from TI for the Stellaris LM3S2110. The TM4C12x series (e.g., TM4C123GH6PM) is the closest functional successor with a Cortex-M4F core, more Flash and SRAM, and a 3.3 V supply — but it requires a firmware port and a board layout change because the pinout and memory map differ.
