DESCRIPTION

· The ADuC832 is a smart transducer front end integrating a 12-bit ADC, dual 12-bit DACs, and an 8-bit MCU.

· Operates from a 32 kHz crystal with an on-chip PLL generating up to 16.78 MHz.

· Features 62 kB Flash/EE program memory, 4 kB Flash/EE data memory, and 2 kB extended RAM.

· Includes additional analog and digital peripherals like DACs, PWM, and serial I/O ports.

FEATURES

· 8-channel, 247 kSPS, 12-bit ADC with ±1 LSB INL and 71 dB SNR.

· Dual 12-bit voltage output DACs and dual output PWM/Σ-Δ DACs.

· On-chip temperature sensor (±3°C) and voltage reference.

· 8051-based core with 16 MHz max, 12 interrupt sources, and dual data pointer.

· On-chip peripherals include UART, I2C, SPI, watchdog timer, and power supply monitor.

APPLICATIONS

· Optical networking and laser power control.

· Base station systems and precision instrumentation.

· Smart sensors and transient capture systems.

· Data acquisition and communication systems.

· Upgrades to ADuC812 systems with enhanced memory and clock options.
