This document describes the features and characteristics of Precision Mixed Signal products, including 10-bit and 8-bit ADCs, programmable gain amplifiers, data-dependent windowed interrupt generator, and built-in temperature sensor.
The C8051F123 is a 64‑pin mixed‑signal microcontroller featuring a high‑speed 8051 core capable of up to 100 MIPS, 128 kB of flash memory, and integrated analog peripherals such as a 10‑bit ADC, two 12‑bit DACs, and temperature sensor. It includes digital peripherals like 32‑port I/O, SMBus/I²C, SPI, two UARTs, and a programmable 16‑bit timer/counter array.
Key electrical characteristics include a supply voltage range of 3.0 V to 3.6 V, typical active current of 50 mA at 100 MHz, and a temperature operating range of –40 °C to +85 °C. The device offers on‑chip JTAG debug, IEEE 1149.1 boundary‑scan, and a programmable PLL for clock generation up to 100 MHz.
