Présentation

Description

W77E058A40DL is an 8‑bit, 8051‑compatible microcontroller in the W77E058 family (often from Winbond/Nuvoton). The “40DL” suffix denotes a 40‑pin package. It provides on‑chip flash memory and RAM, plus common MCU peripherals such as GPIO, timers, and serial interfaces (USART/UART and sometimes SPI/I2C), with additional features that vary by exact variant (and may include ADC/PWM, watchdog, etc.). It targets low‑ to mid‑range embedded control tasks in consumer electronics, appliances, and similar applications. Development uses standard 8051 toolchains; for exact memory sizes, clock options, pinout, electrical specs, and power modes, consult the official datasheet for this specific part.

Features

Exact features depend on the specific revision from the W77E058A40DL family. Typical features for a 40‑pin (DIP-40) 8/16‑bit MCU in this line may include:
- 8-bit core (8051-compatible) with on-chip Flash
- On-chip RAM (a few KB) and Flash memory (several KB)
- I/O: around 20 GPIO pins in a 40-pin package
- Peripherals: UART(s), SPI and/or I2C, Timers/Counters
- Analog: 8/10‑bit ADC (with multiple channels) and PWM outputs
- Interrupt controller with multiple sources
- Watchdog timer
- Clock: external/internal oscillator up to ~20–25 MHz
- Power modes: normal and low-power with wakeup
- In-system programming support
- Development tools and common toolchain compatibility
For precise specifications (exact flash/RAM sizes, peripheral count, package options), please share the datasheet link or confirm the exact variant.

Pinout

- Pin count: 40 pins (40-pin package).
- Function: An 8-bit microcontroller (8051-compatible core) with on-chip flash/ROM and RAM, plus built-in peripherals (GPIO, timers, serial interface) for general embedded control.

Manufacturer

I can’t confirm the manufacturer from my knowledge base. The part number W77E058A40DL appears to be a microcontroller (likely 8‑bit/8051‑class) from a semiconductor vendor, possibly a Chinese IC maker. To identify the exact manufacturer, please share a datasheet, a photo of the package mark, or check distributor catalogs (Digi‑Key, Mouser, Allchips) for the exact part.

Application

- General embedded control using an 8-bit MCU (8051-compatible)
- Consumer electronics and home appliances
- Automotive body electronics and related modules
- Industrial automation, instrumentation, and control panels
- Sensor interfacing, data logging, and small IoT/edge devices
- Remote controls, security devices, and access-control applications

Package

40-pin DIP (DIL) package.
