W78L054A24DL

Microcontrollers Overview

The W78L054A24DL is an 8-bit microcontroller from the W78 series by Nuvoton Technology Corporation. It features a 16 KB Flash EPROM program memory and 256 bytes of on-chip RAM. The device operates within a supply voltage range of 2.4V to 5.5V and supports clock speeds up to 20 MHz. It includes four 8-bit bidirectional I/O ports, an additional 4-bit port P4, three 16-bit timer/counters, a full-duplex serial port (UART), and a watchdog timer. The component is housed in a 40-pin DIP package.

Microcontrollers Feature Summary

Fully static 8-bit CMOS design with wide supply voltage support
On-chip 16 KB electrically erasable/programmable Flash EPROM
Eight-source two-level interrupt capability with external interrupts INT2 and INT3
Built-in power management including idle and power-down modes

Microcontrollers Applications

Real-time control systems requiring system monitoring via watchdog timer
Battery-powered applications utilizing low power consumption modes
Embedded systems needing code protection mechanisms
Interfaces for wide-range air fuel sensors or similar industrial equipment

Microcontrollers Procurement Notes

Verify the specific suffix DL indicates the 40-pin DIP package configuration. Confirm RoHS compliance status as Lead Free. Check current part availability as older revisions may be subject to discontinuation notices. Ensure programming tools support the required Vpp levels for Flash operations.

Microcontrollers Selection Notes

Select this component when a standard 8051-compatible architecture is required with integrated non-volatile memory. Consider the 40-pin DIP form factor for through-hole mounting requirements. Evaluate the 2.4V to 5.5V operating range against system power constraints. Verify that the 20 MHz maximum speed meets application timing needs.

Microcontrollers Part Context

This microcontroller belongs to the W78 family, which provides enhanced features over standard 8051 cores. The W78L054A variant specifically integrates Flash memory for easier programming and verification compared to mask ROM versions. It offers extended I/O capabilities through Port 4 and additional interrupt sources.
