    W78L054C芯片解密时橙盒芯片解密研究所在WINBOND系列IC解密研究中成功破解的典型芯片型号，针对该芯片，我们解密周期短、价格低、可靠性强。这里，我们将针对W78L054C芯片的主要技术特征做简单介绍，供大家参考借鉴。
　 The W78L054C is an 8-bit microcontroller which can accommodate a wide supply voltage range with low power consumption. The instruction set for the W78L054C is fully compatible with the standard 8051. The W78L054C contains an 16K bytes Flash EPROM; 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 Flash EPROM inside the W78L054C allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security.
　　The W78L054C 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.
