C8051T610-GQR

Overview

The C8051T610-GQR is an 8-bit microcontroller from Silicon Labs, featuring a high-speed 8051 core with up to 25 MIPS throughput at a 25 MHz clock. It includes 16 kB of byte-programmable EPROM and 1280 bytes of internal data RAM. The device integrates a 10-bit ADC supporting up to 500 ksps with up to 21 external inputs, two comparators, and a built-in temperature sensor. Digital peripherals include four 16-bit timers, a PCA with five capture/compare modules, UART, SMBus, and SPI. It operates on a supply voltage of 1.8 V to 3.6 V within the -40 °C to +85 °C temperature range.

• Industrial control systems requiring mixed-signal processing
• Battery-powered devices utilizing low-voltage operation
• Sensor interfaces using integrated ADC and temperature sensing
• Communication gateways employing UART, SMBus, and SPI

Procurement Notes

Verify component authenticity through authorized distributors as this part is marked Not Recommended for New Designs. Confirm package integrity upon receipt, as moisture sensitivity requires proper handling. Check revision levels against current design requirements due to potential obsolescence notices. Ensure supply chain stability given the discontinued status.

Selection Notes

Select this MCU for applications needing byte-programmable EPROM and mixed-signal capabilities in a compact LQFP-32 package. Consider the 1.8 V to 3.6 V operating range for low-power designs. Evaluate the 10-bit ADC resolution and speed against application signal requirements. Verify pin compatibility if replacing older C8051 variants.

Part Context

This component belongs to the C8051T61x family of mixed-signal microcontrollers. It shares architectural similarities with other members like the C8051T611 but differs in package and peripheral availability. The T610 specifically utilizes the 32-pin LQFP package, distinguishing it from QFN variants in the same series.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult Silicon Labs for current recommended replacements due to the 'Not Recommended for New Designs' status.
