Analog Devices' ADuC precision analog microcontroller product family combines ARM7 or 8052 microcontroller cores with integrated precision converters, references, and sensor peripherals to target automation, industrial, and automotive applications.
The ADuC7023 and ADuC7122 precision analog microcontrollers use an ARM7 processor with up to 126-kbytes of flash memory to ensure the accurate control of optical drivers and diagnostics. The ADuC7122 features a 13-channel, 12-bit, 1-MSPS SAR (successive-approximation register) ADC (analog-to-digital converters), 12 buffered 12-bit DACs (digital-to-analog converters), a programmable gain amplifier and an on-chip temperature sensor. The device also includes a 32-bit ARM7TDMI processor core operating at 41.78 MHz with 8-kbytes of on-chip SRAM and 128-kbytes of on-chip EEPROM memory with software-triggered in-circuit re-programmability. For fixed frequency optical transceivers, the ADuC7023 offers 8-kbytes of SRAM, 62-kbytes of flash/EEPROM memory, 19 general-purpose I/O (input/output) pins, three general-purpose timers and 16 programmable-logic elements. Analog peripherals include a 12-channel, 12-bit, 1-MSPS ADC, a 16-bit, 6-channel PWM and four buffered 12-bit DACs.
Analog device' Blackfin processor family combines signal-processing capabilities with control functions in a single 16/32-bit core. Target applications include audio and video consumer products, medical electronics, video surveillance, VOIP (voice over Internet Protocol) and industrial instrumentation and control. The 400-MHz Blackfin BF50x series includes optional, integrated dual-SAR 12-bit analog-to-digital converters (ADCs) for more accurate data conversion and 4 MB of on-board executable flash memory. With 11.5 effective number of bits (ENOB), the Blackfin BF506F targets applications such as power inverters, uninterruptible power supplies (UPS), servo controls, and motor controls.
