Product Description

ADuC7027BSTZ62I, Precision Analog Microcontroller, 12-Bit Analog I/O, ARM7TDMI MCU, 80 Pin LQFP, Analog Devices. The ADuC7027 is a fully integrated, 44MIPS, 1 MSPS AD converter, 12-bit data acquisition system incorporating high performance multichannel ADCs, 32-bit MCUs, and Flash/EE memory on a single chip.

The device operates from an on-chip oscillator and a PLL generating an internal high frequency clock of 44 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-bit/32-bit RISC machine, which offers up to 44 MIPS peak performance. Eight kilobytes of SRAM and 62 kilobytes of nonvolatile Flash/EE memory are provided on-chip. The ARM7TDMI core views all memory and registers as a single linear array.
