Overview
W78E054D/W78E052D Data Sheet 1 GENERAL DESCRIPTION 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 8052.
The W78E054D/W78E052D series contains 16K/8K 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 LDROM for loader program, operating voltage from 3.
3V to 5.
5V.
Note: If the applied VDD is not stable, especially with long transition time of power on/off, it’s recommended to apply an external RESET IC to the RST pin for improving the stability of system.
