C8051F040-GQR Description

Short technical summary and product information.

The C8051F040-GQR is an 8-bit microcontroller based on the 8051 core with a pipelined architecture achieving up to 25 MIPS throughput. It integrates 64KB of Flash program memory and 4.25KB of internal data RAM, with an external 64KB data memory interface. Analog peripherals include a 12-bit SAR ADC with 13 external input channels, two 12-bit DACs, three analog comparators, a temperature sensor, and a voltage reference. Digital peripherals include 64 I/O pins, a CAN 2.0B controller, SMBus (I2C), SPI, UART/USART interfaces, and an external bus interface. It also features a brown-out detect/reset, power-on reset, PWM, and watchdog timer. The device operates from 2.7V to 3.6V and over a temperature range of -40°C to 85°C. It is housed in a 100-pin TQFP package (14x14mm) for surface mount assembly.
