C8051T601-GM

Overview

The C8051T601-GM is a mixed-signal microcontroller featuring a high-speed 8051 core with up to 25 MIPS throughput at 25 MHz. It includes 1.5 kB of byte-programmable EPROM code memory and 256 bytes of internal data RAM. The device integrates an SMBus serial port, a hardware-enhanced UART, three 16-bit counter/timers, and a 16-bit programmable counter array (PCA) with capture/compare modules. Analog peripherals consist of a comparator with programmable hysteresis and response time. Operating voltage ranges from 1.8 V to 3.6 V, with an on-chip LDO and voltage supply monitor.

Feature Summary

• Byte-programmable EPROM memory for flexible code storage
• On-chip debug circuitry supporting full-speed non-intrusive in-system debugging
• Integrated SMBus and enhanced UART serial communication interfaces
• Programmable comparator with configurable interrupt or reset capabilities

Applications

• Code development platforms using on-chip debug features
• Systems requiring byte-level EPROM reprogramming
• Applications utilizing SMBus or UART serial communication
• Circuits needing programmable analog comparison functions

Procurement Notes

Verify the component status before procurement as this part is marked Not Recommended for New Designs. Confirm package availability matches the required pinout, typically QFN-11 or SOIC-14 for this model. Ensure design updates consider the obsolescence notice when planning long-term production runs.

Selection Notes

Select this MCU for designs requiring byte-programmable EPROM rather than Flash. It suits applications needing integrated SMBus and UART without external components. The pipelined 8051 core offers high performance within a low-voltage range. Consider the limited I/O count and absence of ADC in this specific variant compared to other family members.

Part Context

This component belongs to the C8051T60x series of mixed-signal MCUs by Silicon Labs. The series shares a common CIP-51 core architecture but varies in memory size and peripheral sets. The C8051T601 specifically provides 1.5 kB EPROM and lacks the 10-bit ADC found in other variants like the C8051T600.
