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.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
