ADI ADUC7061BCPZ32

ARM7®10 МГц32 КБ (16К x 16)

Overview

The ADUC7061BCPZ32 is a Fully Integrated 8kSPS 24-bit Data Acquisition System incorporating high performance multichannel Σ-Δ ADCs, 16-bit/32-bit ARM7TDMI® MCU and Flash/EE memory on a single chip. The ADCs consist of a primary ADC with two differential pairs or four single-ended channels and an auxiliary ADC with up to seven channels. The ADCs operate in single-ended or differential input mode. A single-channel buffered voltage output DAC is available on chip. The DAC output range is programmable to one of four voltage ranges. The ADuC7060 contains four timers. Timer1 is a wake-up timer with the ability to bring the part out of power saving mode. Timer2 is configurable as a watchdog timer. A 16-bit PWM with six output channels is also provided. The ADuC7060 contains an advanced interrupt controller. The vectored interrupt controller (VIC) allows every interrupt to be assigned a priority level. It also supports nested interrupts to a maximum level of eight per IRQ and FIQ.
