Thông số kỹ thuật
This is a fully integrated mixed-signal microcontroller produced by Silicon Labs, built on enhanced 8051 core architecture with streamlined instruction pipeline, delivering faster execution speed than traditional standard 8051 chips and abundant on-chip analog and digital peripherals.
Part Number Definition
C8051F380 is the official core device model of the MCU series. GQ corresponds to LQFP-32 surface mount package specification and industrial temperature grade configuration.
Core and Memory Configuration
The enhanced CIP-51 8051 kernel features a single-cycle instruction execution framework, maximum system clock frequency up to 48MHz. It embeds 32KB in-system programmable Flash memory for program and data storage, with 2304 bytes of general-purpose RAM for temporary data buffering. The chip supports Flash memory read and write operations under running state to realize parameter storage without external storage chips.
Built-in Peripheral Resources
The analog module integrates a 12-bit multi-channel successive approximation ADC with programmable conversion speed and built-in voltage reference, plus a high-speed analog comparator for threshold signal judgment. Digital peripherals include hardware UART, SPI and SMBus communication interfaces, multiple groups of 16-bit programmable counter/timers with PWM generation capability. A dedicated hardware I2C bus and four-channel capture compare unit are reserved. Up to 29 general purpose I/O pins are led out, all supporting crossbar port switching to flexibly map peripheral functions to different pins. Independent watchdog timer and power-on reset circuit are integrated to enhance system anti-interference and fault self-recovery ability.
Power Supply and Working Modes
The chip operates within a supply voltage range of 2.7V to 3.6V. It provides multiple power management modes including normal operation, idle mode and stop mode to lower power consumption when the main task is suspended. An internal precision high-frequency oscillator and low-frequency watchdog oscillator are integrated, allowing the single-chip system to run without external crystal oscillator components.
Packaging and Production Specifications
Package type is 32-pin LQFP with standard surface mount soldering method. It belongs to MSL3 moisture sensitive component, and reflow soldering must be completed within 168 hours after vacuum package opening. Tape-and-reel packaging is available to match automatic patch assembly on production lines.
Environmental and Compliance Requirements
Operating temperature range is -40℃ to +85℃, applicable to conventional industrial and consumer electronic equipment scenarios. The product adopts lead-free manufacturing technology and complies with relevant environmental restriction standards. Compact peripheral integration reduces peripheral circuit quantity and overall PCB layout area.
