　　本文我们以W78LE516单片机为例，简单介绍其主要性能特征，供广大客户在芯片解密项目合作及芯片应用中参考借鉴。
　　The W78LE516 is an 8-bit microcontroller which has an in-system programmable MTP-ROM for firmware updating. The instruction set of the W78LE516 is fully compatible with the standard 8052.The W78LE516 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; 512 bytes of on-chip RAM; four 8-bit bi-directional and bitaddressable 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 MTP-ROM inside the W78LE516 allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security.
　　The W78LE516 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.
