Product details

64 MHz PIC core with 64 KB Flash — what the memory map buys

That memory split — 64 KB Flash for firmware, 4 KB RAM for data buffers, and 1 KB EEPROM for calibration constants or configuration parameters — covers many embedded control applications without external memory. The 64 MHz core gives roughly 16 MIPS throughput, enough for real-time control loops, protocol handling (I²C, SPI, UART/USART, LINbus), and the integrated 24-channel 12-bit ADC and 1-channel 8-bit DAC.

Package and I/O — 28-SOIC with 25 GPIO

Housed in a 28-SOIC (7.50 mm body width) with surface-mount mounting, the part offers 25 I/O lines — enough for a keypad, a small TFT display parallel bus, or a handful of sensor interrupts alongside the serial interfaces. The supplier device package is 28-SOIC.

Frequently asked questions
