C8051T615-GMR

Overview

The C8051T615-GMR is a mixed-signal microcontroller from Silicon Labs, featuring an 8-bit CIP-51 core with up to 25 MIPS throughput at 25 MHz. It integrates 16 kB of byte-programmable EPROM and 1280 bytes of internal data RAM. The device includes a 10-bit ADC capable of up to 500 ksps with up to 17 external inputs, two comparators, and a built-in temperature sensor. Digital peripherals include UART, SMBus, SPI, four 16-bit timers, and a PCA with PWM functionality. It operates on a 1.8 V to 3.6 V supply within a -40°C to +85°C temperature range.

Feature Summary

• Integrates high-speed 8051-compatible core with pipelined architecture for efficient instruction execution.
• Features non-volatile byte-programmable EPROM memory for code storage and field upgrades.
• Includes analog subsystem with 10-bit ADC, programmable comparators, and temperature sensing capabilities.
• Provides flexible digital I/O via programmable crossbar and multiple serial communication interfaces.

Applications

• Industrial control systems requiring robust analog signal processing
• Battery-powered devices utilizing low voltage operation and power management modes
• Data acquisition systems using the integrated high-speed ADC

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required package type and temperature grade. Check for current lifecycle status as this series may be designated as Not Recommended for New Designs. Ensure compatibility with existing development tools such as Silicon Labs IDE or Keil C51 before procurement.

Selection Notes

Select this model when byte-programmable EPROM is preferred over Flash for specific rewriting requirements. Consider the 28-pin QFN package for space-constrained designs. Evaluate the 10-bit ADC resolution and speed against application needs. Verify that the 1.8 V to 3.6 V supply range aligns with system power rails. Assess peripheral counts including UART, SPI, and timer availability for interface requirements.
