Category: Main/ II. Electronics components & Development Tools/II.2.a. Nuvoton 8-bit microcontrollers with 8051-core
| | | | | ◊ Đặc điểm chính: | | Họ vi điều khiển W78E054D/W78E052D của Nuvoton là họ MCU 8051 có cấu hình chuẩn, tương thích Pin-to-pin và mã trình phần mềm (firmware) với dòng MCU 80C51 chuẩn; Vì vậy, nó dùng để thay thế tương đương hoàn toàn cho dòng AT89C51, AT89C52 và AT89S51, AT89S52 của hãng ATMEL. Cho nên, bạn chỉ cần nạp firmware đã có đang dùng cho AT89S52 của ATMEL vào cho chip W78E052D này của Nuvoton rồi cắm vào mạch cũ đã dùng chip AT89S52 thì mạch của bạn vẫn chạy hoạt động tốt giống hệt như bạn đang dùng chip AT89S52 vậy.
Ưu điểm vượt trội của chip W78E054D/W78E052D là dải áp hoạt động rộng 2.4~5.5V, các cổng I/O có dòng cao đủ sáng LED, tần số thạch anh tối đa tới 40MHz (chế độ 12T) hoặc 20MHz (chế độ 6T) và chạy bền, kháng nhiễu tốt, ổn định hơn nhiều chip AT89 của ATMEL.

The W78E054D/W78E052D series is an 8-bit microcontroller which can accommodate a wider frequency range with low power consumption. The instruction set for the W78E054D/W78E052D series is fully compatible with the standard 8051. The W78E054D/W78E052D series contains 16K/8K/4K bytes Flash EPROM programmable by hardware writer; a 256 bytes RAM; four 8-bit bi-directional (P0, P1, P2, P3) and bit-addressable I/O ports; an additional 4-bit I/O port P4; three 16-bit timer/counters; a hardware watchdog timer and a serial port. These peripherals are supported by 8 sources 4-level interrupt capability. To facilitate programming and verification, the Flash EPROM inside the W78E054D/W78E052D series allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security. The W78E054D/W78E052D series microcontroller has two power reduction modes, idle mode and power-down mode, both of which are software selectable. The idle mode turns off the processor clock but allows for continued peripheral operation. The power-down mode stops the crystal oscillator for minimum power consumption. The external clock can be stopped at any time and in any state without affecting the processor. The W78E054D/W78E052D series contains In-System Programmable (ISP) 2KB AP Flash EPROM for loader program; operating voltage from 2.4V to 5.5V. - Fully static design 8-bit CMOS microcontroller
- Pin and Instruction-set compatible with 80C52
- 256 bytes of on-chip scratchpad RAM
- 16K/8K bytes electrically erasable/programmable Flash EPROM
- 2K bytes LDROM support ISP function
- 64KB program memory address space

- 12 clocks per machine cycle operation (default), Speed up to 40 MHz
- Four 8-bit bi-directional ports with high sink current for LED driver
- 8-sources, 4-level interrupt capability
- One extra 4-bit bit-addressable I/O port, additional / (available on PQFP, PLCC and LQFP package)
- Three 16-bit timer/counters
- One full duplex serial port
- Watchdog Timer
- Eight sources, two-level interrupt capability
- EMI reduction mode
- Software Reset
- Built-in power management with idle mode and power down mode
- Code protection
