W78E054D/W78E052D Data Sheet
1 GENERAL DESCRIPTION
The W78E054D/W78E052D series is an 8-bit microcontroller which can accommodate a wider fre-
quency 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 ad-
ditional 4-bit I/O port P4; three 16-bit timer/counters; a hardware watchdog timer and a serial port. The-
se 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 sys-
tem.
