产品概览
The PIC18LF452-I/PT from Microchip Technology is a high-performance 8-bit PIC18 enhanced flash microcontroller with 32 KB Flash, 1.5 KB SRAM, and 256 bytes EEPROM. Running at up to 40 MHz with 10 MIPS throughput, it features a 10-bit ADC, multiple communication interfaces (USART, SPI, I2C), and a robust peripheral set in a TQFP-44 package. The LF variant operates down to 2.0V for low-power applications.
