Some of the old and out of date devices need to be repaired while the head of the device: Microcontroller has burned out and unable to be used anymore, at this time engineer need to get microcontroller replaced so Retrieve Nuvoton Microcontroller W77E54 Program become a necessary step to proceed with, today we would like to introduce how the W77E54 is working, start from the general introduction and main features:
The W77E54 is an 8-bit microcontroller which can accommodate a wider frequency range with low power consumption. The instruction set for the W77E54 is fully compatible with the standard 8051. The W77E54 contains an 4K bytes Flash EPROM; a 128 bytes RAM; four 8-bit bi-directional and bit-addressable I/O ports; an additional 4-bit I/O port P4; two 16-bit timer/counters when Retrieve Nuvoton Microcontroller W77E54 Program; a hardware watchdog timer and a serial port. These peripherals are supported by seven sources two-level interrupt capability. To facilitate programming and verification, the Flash EPROM inside the W77E54 allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security.
The W77E54 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 after Retrieve Nuvoton Microcontroller W77E54 Program.
