ADUC7061:  Low-Power, Precision Analog Microcontroller, Dual Σ-Δ ADCs, Flash/EE, ARM7TDMI

Product Details

The ADuC7060/ADuC7061 are fully integrated, 8 kSPS, 24-bit data acquisition systems incorporating high performance multi-channel sigma-delta (Σ-Δ) analog-to-digital converters (ADCs), 16-bit/ 32-bit ARM7TDMI® MCU, and Flash/EE memory on a single chip.

The ADCs consists of a 5-channel primary ADC and up to an 8-channel auxiliary ADC. The ADCs operate in single-ended or differential input modes. A single channel buffered voltage output DAC is available on-chip. The DAC output range is programmable to one of two voltage ranges.

The devices operate from an on-chip oscillator and a PLL gene-rating an internal high frequency clock up to 10.24 MHz. The microcontroller core is an ARM7TDMI, 16-bit/32-bit RISC machine offering up to 10 MIPS peak performance. 4 kB of SRAM and 32 kB of nonvolatile Flash/EE memory are provided on-chip. The ARM7TDMI core views all memory and registers as a single linear array.

The ADuC7060/ADuC7061 contain four timers. Timer 1 is wake-up timer with the ability to bring the part out of power saving mode. Timer 2 may be configured as a watchdog timer. A 16-bit PWM with six output channels is also provided.

The ADuC7060/ADuC7061 contain 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. When IRQ and FIQ interrupt sources are combined, a total of 16 nested interrupt levels are supported.On-chip factory firmware supports in-circuit serial download via the UART serial interface ports and nonintrusive emulation via the JTAG interface.

The parts operate from 2.375 V to 2.625 V over an industrial temperature range of −40°C to +125°C.
