3 / 43 page  W78E365/W78E365A Publication Release Date: January 10, 2007 - 3 - Revision A9 ftware ammable port (I/O, interrupt, Chip select function) al port out level interrupt capability − Lead Free (RoHS) PLCC 44: W78E365A40PL − Lead Free (RoHS) PQFP 44: W78E365A40FL − Lead Free (RoHS) LQFP 48: W78E365A40LL 1. GENERAL DESCRIPTION The W78E365 is an 8-bit microcontroller which has an in-system programmable Flash EPROM for firmware updating. The instruction set of the W78E365 is fully compatible with the standard 8052. The W78E365 contains a 64K bytes of main Flash APROM and a 4K bytes of auxiliary Flash LDROM which allows the contents of the 64KB main APROM to be updated by the loader program located at the LDROM; 256+1K 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; a serial port. These peripherals are supported by a eight sources two-level interrupt capability. To facilitate programming and verification, the ROM inside the W78E365 allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security. The W78E365 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. 2.
