W78E516B-40 - Brand New Winbond Electronics Microcontrollers
-
Description
The W78E516B-40 is an 8-bit microcontroller in the product category of Microcontrollers. It features an in-system programmable MTP-ROM for firmware updating, making it easy to update the firmware. The instruction set of the W78E516B-40 is fully compatible with the standard 8052. It contains a 64K bytes of main MTP-ROM and a 4K bytes of auxiliary MTP-ROM which allows the contents of the 64KB main MTP-ROM to be updated by the loader program located at the 4KB auxiliary MTP-ROM. It also includes 512 bytes of on-chip RAM, four 8-bit bi-directional and bit addressable I/O ports, an additional 4-bit port P4, three 16-bit timer/counters, and a serial port. These peripherals are supported by an eight sources two-level interrupt capability.
