The Microchip PIC18F55Q43-E/PT is an 8-bit PIC MCU from the XLP 18F family, clocked at 64 MHz with 32 KB Flash, 2 KB RAM, and 1 KB EEPROM on-chip.
Forty-four I/O lines are available. The part includes a 43-channel 12-bit ADC and a single 8-bit DAC. Serial interfaces include I2C, SPI, UART/USART, and LINbus.
Microchip lists the PIC18F55Q43-E/PT as Active.
The package is a 48-TQFP Exposed Pad.
The difference is the temperature grade. For applications that see ambient above 85°C, the -E/PT is the correct choice.
Yes. The PIC18F55Q43-E/PT uses Microchip's standard ICSP (In-Circuit Serial Programming) interface, which is supported by PICkit 3, PICkit 4, and PICkit 5 programmers. The 44 I/O lines include the ICSPDAT and ICSPCLK pins for programming and debugging.
