ADuC7129BSTZ126-RL: Precision Analog Microcontroller ARM7TDMI® MCU with 12-Bit ADC and DDS DAC
The ADuC7128/ADuC7129 are fully integrated, 1 MSPS, 12-bit data acquisition systems incorporating a high performance, multi-channel analog-to-digital converter (ADC), DDS with line driver, 16-/32-bit MCU, and Flash/EE memory on a single chip.
The ADC consists of up to 14 single-ended inputs. The ADC can operate in single-ended or differential input modes. The ADC input voltage is 0 to VREF. Low drift band gap reference, temperature sensor, and voltage comparator complete the ADC peripheral set.
The ADuC7128/ADuC7129 integrate a differential line driver output. This line driver transmits a sine wave whose values are calculated by an on-chip DDS or a voltage output determined by the DACDAT MMR.
The devices operate from an on-chip oscillator and PLL, generating an internal high frequency clock of 41.78 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 ARM7TDMI®, 16-/32-bit reduced instruction set computer (RISC), offering up to 41 MIPS peak performance. There are 126 kB of nonvolatile Flash/EE provided on-chip, as well as 8 kB of SRAM. The ARM7TDMI core views all memory and registers as a single linear array.
On-chip factory firmware supports in-circuit serial download via the UART serial interface port, and nonintrusive emulation is also supported via the JTAG interface. These features are incorporated into a low cost QuickStart™ development system supporting this MicroConverter® family.
The parts operate from 3.0 V to 3.6 V and are specified over an industrial temperature range of −40°C to +125°C. When operating at 41.78 MHz, the power dissipation is 135 mW. The line driver output, if enabled, consumes an additional 30 mW.
