GENERAL DESCRIPTION
The W78E054D/W78E052D/W78E051D series is an 8-bit microcontroller which can accommodate a
wider frequency range with low power consumption. The instruction set for the W78E054D/
W78E052D/ W78E051D series is fully compatible with the standard 8052.
The W78E054D/W78E052D/W78E051D series contains 16K/8K/4K bytes Flash EPROM programma-
ble 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 pro-
gramming and verification, the Flash EPROM inside the W78E054D/W78E052D/W78E051D 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/W78E051D 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 proc-
essor clock but allows for continued peripheral operation. The power-down mode stops the crystal os-
cillator for minimum power consumption. The external clock can be stopped at any time and in any
state without affecting the processor. The W78E054D/W78E052D/W78E051D series contains In-
System Programmable (ISP) 2KB LD Flash EPROM for loader program, operating voltage from 3.3V
to 5.5V.
