ADUC842BS62-5

Manufacturer

Analog Devices, Inc. (ADI). Y-IC is a quality distributor of ADI. We supply original parts and deliver the best products and services to every customer.

Detailed Description

ADuC842 MicroConverter series device combining an 8052-compatible microcontroller with precision mixed-signal analog functions on one chip. Integrates MCU, ADC/DAC, voltage reference, clocking, and rich digital interfaces for measurement, control, and smart sensing applications. Delivered in a QFP package; the BS62-5 suffix identifies the specific package/variant as defined in the official datasheet.

Key Features

8052-compatible core for easy reuse of existing code

Integrated precision analog: on-chip ADC, DAC, voltage reference (see datasheet for the exact feature set of ADUC842BS62-5)

On-chip nonvolatile Flash program memory and SRAM

Multiple serial interfaces: UART, SPI, I2C

Timers/counters, PWM, watchdog

On-chip oscillator and flexible clock options

Power management: brownout/reset, low-power modes

Industrial temperature range support

QFP package for reliable SMT assembly

Key Advantages

Single-chip mixed-signal solution reduces BOM and board space

8052 instruction set lowers migration effort from legacy systems

Precision analog built-in improves measurement accuracy and reduces external components

Lower power than discrete designs

Robust peripherals simplify design and shorten time to market

Proven ADI MicroConverter platform with strong ecosystem

Packaging

Type: QFP (Quad Flat Package), low-profile LQFP style

Material: Molded plastic (epoxy) with copper leadframe; RoHS/lead-free options typically available

Size: Standard LQFP body; verify exact outline and height in the ADUC842BS62-5 datasheet

Pin configuration: Fine-pitch gullwing leads; multi-function pins for analog inputs/outputs, reference, serial interfaces (UART/SPI/I2C), GPIO, power and ground

Thermal characteristics: Typical θJA/θJC depend on PCB layout, copper area, and airflow; follow datasheet and JEDEC guidelines for thermal design and derating

Electrical properties: Nominal operation around 5 V for the “-5” variant; digital I/O compatible with 5 V logic; ESD ratings and absolute maximums per ADI specifications (see datasheet for limits and recommended operating conditions)

Lifecycle

Status: Mature ADI product line. Availability may vary by region and package. Check current supply status before committing to production.

Recommended equivalents or alternatives:

- ADuC841 (same family, similar MCU with different memory/peripheral mix)

- ADuC843 (same family, enhanced memory/peripherals)

- ADuC845 / ADuC846 / ADuC847 (MicroConverters with higher-resolution sigma-delta ADCs for precision sensing needs)

- For 32-bit migration: ADuC702x series (ARM7-based mixed-signal), depending on your performance and compatibility requirements
