Product details

It carries 32 KB of Flash, 12 KB of SRAM, and 2 KB of EEPROM on-chip — enough for a moderate control loop or sensor fusion algorithm without external memory. The 12-channel 12-bit ADC and CAN, I2C, SPI, UART, IrDA, Microwire, and SSI interfaces make it a natural fit for industrial motor drives, automotive body controllers, and factory-automation I/O modules that need mixed-signal and fieldbus connectivity in a single package.

The 80 MHz core with a hardware FPU and DSP extensions handles real-time control loops. The 12 KB SRAM is tight for heavy buffering.

The 64-LQFP package (10x10 mm) reflows on a standard profile.
