ADUC814BRU Description

Short technical summary and product information.

The ADUC814BRU is a microcontroller from Analog Devices based on the 8051 core, featuring 8KB of Flash program memory, 256 bytes of RAM, and 640 bytes of EEPROM data memory. It operates at clock speeds up to 16.78 MHz via an on-chip PLL from a 32 kHz external crystal.

 

The device integrates a 6-channel, 12-bit ADC with a sampling rate of 247 kSPS and a dual 12-bit DAC with 15 µs settling time. On-chip peripherals include POR, PSM, temperature sensor, watchdog timer, UART, SPI, I2C, timer/counters, RTC, and voltage reference.

 

With 11 programmable I/O lines and a supply voltage range of 2.7V to 5.5V, the ADUC814BRU is suitable for industrial and automotive applications. It consumes 3 mA in normal mode and 15 µA in power-down mode.

 

The device is housed in a 28-lead TSSOP package (4.4mm x 9.7mm) for surface mount assembly and is specified for operation from -40°C to +125°C.
