The ADUC7061 is fully integrated 24-bit data acquisition systems incorporating high performance multi-channel sigma-delta and analog-to-digital converters, 16-bit/ 32-bit ARM7TDMI® MCU and Flash/EE memory on a single chip. 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 10.24MHz. The microcontroller core is an ARM7TDMI, 16-bit/32-bit RISC machine offering up to 10 MIPS peak performance. 4kB of SRAM and 32kB of nonvolatile Flash/EE memory are provided on-chip. The ARM7TDMI core views all memory and registers as a single linear array.
The 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.
