ADUC814 General Description

The ADuC814 is a fully integrated 247 kSPS, 12-bit data acquisition system incorporating a high performance multichannel ADC, an 8-bit MCU, and program/data Flash/EE memory on a single chip.

This low power device operates from a 32 kHz crystal with an on-chip PLL generating a high frequency clock of 16.78 MHz. This clock is, in turn, routed through a programmable clock divider from which the MCU core clock operating frequency is generated.

The microcontroller core is an 8052 and is compatible with an 8051 instruction. 8 kBytes of nonvolatile Flash/EE program memory are provided on-chip. 640 bytes of nonvolatile Flash/EE data memory and 256 bytes RAM are also integrated on-chip.

The ADuC814 also incorporates additional analog functionality with dual 12-bit DACs, a power supply monitor, and a band gap reference. On-chip digital peripherals include a watchdog timer, time interval counter, three timer/counters, and two serial I/O ports (SPI and UART).

On-chip factory firmware supports in-circuit serial download and debug modes (via UART), as well as single-pin emulation mode via the DLOAD pin. The ADuC814 is supported by a QuickStart™ Development System.
