橙盒NEC解密技术——UPD78F0562单片机解密

　　橙盒科技早期主要致力于技术研究领域，在幕后为各类同行业者提供多种高难度IC解密方案的开发，近年来，随着我们在互联网上以及整个行业内的影响越来越大，也逐渐被更多客户所熟知。
　　NEC系列单片机解密难度大，且几乎每款芯片具体解密方法都不同，目前没有现成解密方案可用，因此，对于该系列芯片，我们工程师需要重新来开发破解方法，所需周期一般需要20个工作日左右，也希望客户在充分考虑产品开发价值的同时核算好产品开发周期。
　　UPD78F0562芯片主要特性如下，供广大需求客户及其他解密工程师参考借鉴：
　　78K0 CPU core
　　Low power consumption (VDD = 3.0 V)
　　* Internal high-speed oscillation mode:   220
　　* STOP mode:   0.65
　　Clock
　　* High-speed system clock … Selected from the following three sources
　　- Ceramic/crystal oscillator:   1 to 10 MHz
　　- External clock:   1 to 10 MHz
　　- Internal high-speed oscillator:   4 MHz ± 2 % (-20 to +70°C), or 8 MHz ± 3 %(-40 to +85°C)
　　* Low-speed system oscillator   30 kHz ± 10 % … Watchdog timer, timer clock in intermittent operation
　　* Subsystem clock:   Clock to operate the real-time counter mainly
　　Timer
　　* 16-bit timer/event counter …  PPG output, capture input, external event counter input
　　* 8-bit timer H …  PWM output
　　* 8-bit timer/event counter 5 … PWM output, external event counter input
　　* Watchdog timer … Operable with low-speed internal oscillation clock
　　* Real-time counter … Available to count up in year, month, week, day, hour, minute, and second units
　　Serial interface
　　* UART …  Asynchronous 2-wire serial interface
　　* IICA … Clock synchronous 2-wire serial interface, multimaster supported, standby can be released upon address match in slave mode
　　* CSI … Clock synchronous 3-wire serial interface
　　10-bit resolution A/D conversion：6ch
　　Operational amplifier (products with operational amplifier only):1ch
　　Power-on-clear (POC) circuit
　　Low-voltage detector (LVI) (An interrupt/reset (selectable) is generated when the detection voltage is reached))
　　* Detection voltage: Selectable from sixteen levels between 1.91 and 4.22 V  Single-power-supply flash memory
　　* Flash self programming enabled
　　* Software protection function: Protected from outside party copying (no flash reading command)
　　Safety function
　　* Watchdog timer operated by clock independent from CPU
　　… A hang-up can be detected even if the system clock stops
　　* Supply voltage drop detectable by LVI
　　… Appropriate processing can be executed before the supply voltage drops below the operation voltage
　　* Equipped with option byte function
　　… Important system operation settings set in hardware
　　On-chip debug function …Available to control for the target device, and to reference memory
　　Assembler and C language supported
　　Development tools
　　* Support for full-function emulator (IECUBE), and simplified emulator (MINICUBE2)
　　Power supply voltage: VDD = 1.8 to 5.5 V
　　Operating ambient temperature: TA = -40 to +85°C
