Product Overview

The ADUC834BSZ is a 8-bit Microcontroller incorporates two high-resolution Σ-Δ ADCs and program/data flash/EE memory on a single chip. The two independent ADCs (primary and auxiliary) include a temperature sensor and a PGA. The device operates from a 32kHz crystal with an on-chip PLL generating a high frequency clock of 12.58MHz. This clock is routed through a programmable clock divider from which the MCU core clock operating frequency is generated. The microcontroller core is an 8052 and therefore 8051 instruction set compatible with 12 core clock periods per machine cycle. 62kB of nonvolatile Flash/EE program memory, 4kB of nonvolatile Flash/EE data memory and 2304byte of data RAM are provided on-chip. The program memory can be configured as data memory to give up to 60kB of NV data memory in data logging applications.
  • 2 Independent ADCs (16-bit and 24-bit resolution)
  • 24-bit No missing codes, primary ADC
  • 21-bit RMS Effective resolution at 20Hz
  • Offset drift 10nV/ C, gain drift 0.5 ppm/C
  • Flash/EE, 100 years retention, 100k cycles endurance
  • 3 Levels of flash/EE program memory security
  • In-circuit serial download (no external hardware)
  • High speed user download (5 Seconds)
  • 8051 Compatible instruction set
  • 32kHz External crystal
  • On-chip programmable PLL (12.58MHz Max)
  • 3x 16-bit Timer/counters
  • 11 Interrupt sources, Two priority levels
  • Dual data pointer, Extended 11-bit stack pointer
  • Internal power on reset circuit
  • 12-bit Voltage output DAC
  • Dual 16-bit Σ-Δ DACs/PWMs
  • On-chip temperature sensor
  • Time interval counter (wake-up/RTC timer)
  • High speed baud rate generator (Including 115,200)
