W78E052DDG – 8-Bit CMOS Microcontroller Nuvoton – DIP-40 Package
The W78E054D/W78E052D series is an 8-bit microcontroller that 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 of 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. Tags, W78E054DDG, W78E051D, W78E052DDG, W78E052, W78E052DDG.
