Product details

Memory budget — 8 KB Flash, 1.5 KB RAM, 2 KB EEPROM

The 8 KB Flash (8K x 8) is the program store; with a 16 MHz core, the flash wait state matters for tight loops. The 1.5 KB RAM is modest — enough for small data buffers and stack for sensor fusion or control loops. The 2 KB EEPROM, separate from Flash, allows non-volatile parameter storage without wearing the program memory. For a design logging calibration data or configuration, the EEPROM endurance is a factor to budget.

The 3.6 V maximum covers standard 3.3 V logic with margin. This range simplifies power rail design in mixed-voltage systems — no separate 5 V supply needed, and the MCU can interface directly with 1.8 V sensors.
