W78LE52F-24规格书详情
GENERAL DESCRIPTION
The W78LE52 is an 8-bit microcontroller which can accommodate a wider frequency range with low power consumption. The instruction set for the W78LE52 is fully compatible with the standard 8051. The W78LE52 contains an 8K bytes MTP ROM (Multiple-Time Programmable ROM); a 256 bytes RAM; four 8-bit bi-directional 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 eight sources two-level interrupt capability. To facilitate programming and verification, the MTP-ROM inside the W78LE52 allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security.
