The MPC82G516A is a high-performance 1-T architecture 80C51 single-chip microcontroller with a CPU instruction execution time of 1 to 7 clock cycles (about 6 to 7 times that of the standard 8051) and an 8051-compatible instruction set. Therefore, at the same performance, the MPC82G516A can run at much lower speeds, thus greatly reducing power consumption.
RayMing Technology’s MPC82G516A MCU decryption program is mature and can complete MPC82G516A MCU decryption and other MPC Megawin chip decryption in a short time. If you have MPC82G516A MCU decryption and other shengquan Megawin chip decryption needs, please consult 0755-27389625.
MPC82G516A has 64K bytes of embedded flash code and data. Program the Flash memory in parallel mode or serial mode, in-system programming (ISP) and in-circuit programming (ICP) functions. It also provides In Application Programming (IAP) functionality. ISP and ICP allow users to download new code without having to remove the microcontroller from the actual final product; IAP means that the device can write non-volatile data to the Flash memory while the application program is running. No external high voltage is required for programming, thanks to its built-in charge pump circuitry.

Additional 8051 MCU standard features (such as 256 bytes of on-chip transient RAM, four 8-bit I/O ports, three timers/counters, full-duplex serial port, and a multi-source, 4-stage interrupt controller) and many system-level features have been incorporated into the MPC82G516A. The features are 1024 bytes of on-chip extended RAM (XRAM), an additional I/O port (P4), 10-bit ADC, PCA, and a new IAP. The MPC82G516A features a 10-bit ADC, PCA, SPI, secondary UART, keyboard interrupt, a watchdog timer, and more. These additional features are discrete components that greatly reduce board space and system cost and can also be carried out, making the MPC82G516A a powerful microcontroller for a wide range of applications.
The MPC82G516A has two power saving modes and an 8-bit system clock divider to reduce power consumption. In idle mode, the CPU is frozen while the peripheral modules and interrupt system remain operational.
In power-down mode the values of RAM and special function registers are saved and all other functions are disabled, and most importantly, the device in power-down mode can be woken up by external interrupts. Moreover, the user can further reduce power consumption by using an 8-bit system clock divider to slow down operation.
In addition, the MPC82G516A is equipped with AMICCOM’s proprietary On-Chip Debug (OCD) interface for In Circuit Emulator (ICE). The OCD interface provides non-intrusive debugging of the chip and system without any target resource consumption. Some features are necessary for ICE support, such as reset, run, stop, single-step, run-to-cursor and breakpoint settings. Users do not need to prepare any development board for firmware development process, or socket adapters in traditional ICE probes. All the user needs to do is to prepare a dedicated OCD interface with a 4-pin connector. This powerful feature makes development very easy for any user.
