Overview
The ADUC848BCPZ62-5 is a microcontroller unit (MCU) from Analog Devices Inc., part of the ADuC848 family. This device is a single-cycle, 12.58 MIPs, 8052 core upgrade, integrating high-resolution Σ-Δ ADCs with embedded Flash and data memory. It is designed as a complete smart transducer front end, suitable for applications requiring multiple analog-to-digital conversion channels.
The ADUC848BCPZ62-5 operates with a fast 8-bit MCU and includes program and data Flash/EE memory on a single chip. It supports in-circuit serial download and debug modes via UART, as well as single-pin emulation mode via the EA pin. The device is supported by the QuickStart™ development system, which features low-cost software and hardware development tools.
