GENERAL DESCRIPTION

Dual Data Pointer, Extended 11-Bit Stack Pointer

On-Chip Peripherals

The ADuC846 is a complete smart transducer front end, integrating

two high resolution sigma-delta ADCs, an 8-bit MCU, and

program/data Flash/EE memory on a single chip.

Internal Power on Reset Circuit

12-Bit Voltage Output DAC

Dual 16-Bit S-D DACs/PWMs

The two independent ADCs (primary and auxiliary) include a

temperature sensor and a PGA (allowing direct measurement of low

level signals). The ADCs with on-chip digital filtering and

programmable output data rates are intended for the measurement of

wide dynamic range, low frequency signals, such as those in weigh

scale, strain-gage, pressure transducer, or temperature measurement

applications.

On-Chip Temperature Sensor

Dual Excitation Current Sources

Time Interval Counter (Wakeup/RTC Timer)

2 ®

UART, SPI , and I C Serial I/O

High Speed Baud Rate Generator (incl 115,200)

Watchdog Timer (WDT)

Power Supply Monitor (PSM)

The device operates from a 32 kHz crystal with an on-chip PLL

generating a high frequency clock of 12.58 MHz. This clock is routed

through a programmable clock divider from which the MCU core

clock operating frequency is generated. The microcontroller core is an

optimized single cycle 8052 offering up to 12.58MIPs performance

while maintaining the 8051 instruction set compatibility.

Power

Normal: 2.3mA Max @ 3.6 V (Core CLK = 1.57 MHz)

Power-Down: 20µA Max with Wakeup Timer Running

Specified for 3 V and 5 V Operation

Package and Temperature Range

52-Lead MQFP (14 mm × 14 mm), –40°C to +125°C

56-Lead CSP (8 mm × 8 mm), –40°C to +85°C

APPLICATIONS

62 Kbytes of nonvolatile Flash/EE program memory, 4 Kbytes of

nonvolatile Flash/EE data memory, and 2304 bytes of data RAM are

provided on-chip. The program memory can be configured as data

memory to give up to 60 Kbytes of NV data memory in data logging

applications.

Intelligent Sensors

WeighScales

Portable Instrumentation, Battery Powered Systems

4-20mA Transmitters

On-chip factory firmware supports in-circuit serial download and

debug modes (via UART), as well as single-pin emulation mode via

the EA pin. The ADuC846 is supported by a QuickStart™

development system featuring low cost software and hardware

development tools.
