Supply SONIX SN8F5703JG 8MHz Enhancement 8051-Based CPU 8-Bit Microcontroller

[Shenzhen Mingjiada Electronics Co., Ltd.] Long Term Supply (SONIX) SN8F5703JG 8051 Microcontroller IC, Below is information about the MCU SN8F5703JG:

Part Number: SN8F5703JG

Package: QFN24

Type: 8051-Based Microcontroller

SN8F5703JG is an 8-bit microcontroller compatible with the MCS-51 instruction set and is up to 12.1 times more efficient than the original 8051 at the same execution frequency standard. At the same time, SN8F5703JG advanced semiconductor technology extends the operating voltage range (1.8 V to 5.5 V) and operating temperature (-40°C to 85°C), enabling high-speed operation in a variety of applications.

The SN8F5703JG microcontroller features 8 KB of ROM, 256 bytes of IRAM and 256 bytes of XRAM, as well as a 12-bit high-precision ADC, an operational amplifier (OP-Amp), a comparator circuit, a PWM generator, three 16-bit timers, and communication interfaces for UART, SPI, and I2C to meet the needs of consumer electronics, home appliances, and other applications. The SN8F5703JG is designed to meet the needs of consumer electronics, home control, and brushless motor control applications.

SN8F5703JG——Pin Configurations (QFN24)

SN8F5703JG is an enhanced 8051 microcontroller and is fully compatible with the MCS-51 instruction set, so SN8F5703JG can be emulated with today's popular compilation environments (e.g. Keil C51). Overall, the SN8F5000 CPU is 9.4 to 12.1 times faster than the original 8051 at the same frequency.

Memory Architecture Of SN8F5703JG
SN8F5703JG has three built-in memories: internal RAM (IRAM), external RAM (XRAM), and programme memory (IROM). The internal RAM consists of 256 bytes and has high access performance (supports direct and indirect addressing). External RAM consists of 256 bytes, but requires longer access cycles. The programme memory is an 8KB FLASH memory with a maximum access speed of 8MHz.

SN8F5703JG has a built-in ROM encryption mechanism to prevent cracking of the Flash ROM data. When the encryption function is enabled, the contents of the ROM cannot be read out, and all ROM addresses can only be read up to 0x00.
