A96G140KD

The A96G140KD is an 8-bit CMOS microcontroller based on an M8051-compatible core, designed for embedded control applications requiring balanced performance, on-chip integration and flexible power options. It combines up to 64 Kbytes of on-chip Flash, 2.5 Kbytes of RAM, a 12-bit ADC and multiple timers/PWM channels to streamline sensor interfacing, motor and actuator control, and user‑interface tasks.

With a wide operating voltage range (1.8–5.5 V), support for internal and external oscillators and a compact 32‑pin SOP package, the A96G140KD is suited to space-constrained designs across consumer, home‑appliance and general industrial control segments.

Key Features

• Core M8051-compatible 8‑bit CISC core with up to 16 MHz main clock operation (minimum instruction execution time 125 ns at 16 MHz).
• Memory 64 Kbytes on‑chip Flash (ISP capable, 30,000 erase/program cycles endurance) and 2.5 Kbytes RAM (256 bytes IRAM + 2,304 bytes XRAM).
• Analog 12‑bit A/D converter with up to 16 input channels and 133 ksps sampling capability for precise sensor acquisition.
• Timers & PWM Comprehensive timer set including five 16‑bit timers, one 8‑bit timer, basic interval timer, watchdog timer and dedicated buzzer/PWM outputs for motor, PWM and timing control.
• Serial Interfaces Flexible serial communications: USI0/1 supporting USART/SPI/I2C configurations and an additional USART channel with receiver timeout and baud stability features.
• GPIO & High‑Current Port 30 general purpose I/O pins with dedicated high‑sink current ports for driving LEDs and other loads.
• Power & Clock On‑chip oscillator (internal RC and external crystal options), POR, low voltage reset/indicator (multiple threshold levels), and power‑saving modes (STOP, IDLE) to optimize energy use.
• Reliability & Safety Watchdog timer, watch timer intervals and power reset circuitry to improve system robustness.
• Environmental & Packaging Industrial operating range of −40 °C to +85 °C and supplied in a 32‑pin SOP surface‑mount package for compact PCB implementations.

Typical Applications

• Home Appliances — Control panels, motor drive timing and user interfaces using integrated timers, PWM outputs and high‑current LED ports.
• Consumer Electronics — Sensor hubs and handheld devices benefitting from the 12‑bit ADC, compact package and wide supply range.
• Industrial Control — Low‑to‑mid complexity control tasks and peripheral management where reliability features (WDT, POR, LVR) and industrial temperature operation are required.
• Motor & Actuator Control — PWM generation, multiple 16‑bit timers and buzzer output for precise control and feedback functions.

Unique Advantages

• High on‑chip integration: 64 Kbytes Flash, 2.5 Kbytes RAM, ADC and multiple timers reduce BOM and PCB area by minimizing external components.
• Flexible analog front end: 12‑bit, multi‑channel ADC enables accurate sensor interfacing without an external converter.
• Wide supply and temperature range: Operates from 1.8 V to 5.5 V and from −40 °C to +85 °C, enabling use across battery‑powered and industrial environments.
• Robust system features: POR, programmable LVR/LVI levels, watchdog and watch timers simplify safety and reliability design.
• In‑System Programmable Flash: 64 Kbytes of ISP Flash with high endurance (30,000 cycles) for field updates and iterative development.
• Compact, production‑friendly package: 32‑pin SOP surface‑mount package supports compact designs and automated assembly.
