C8051T630-GDI

Overview

The C8051T630-GDI is an 8-bit microcontroller from Silicon Labs, part of the C8051T63x series. It features an 8051 core with a maximum clock frequency of 25 MHz. The device includes 8 kB of OTP EPROM program memory and 768 bytes of data RAM. It is housed in a QFN-20 package and supports operating temperatures from -40°C to +85°C. Power supply ranges from 1.8 V to 3.6 V. Key peripherals include a 10-bit ADC with 16 channels, four 16-bit timers, and interfaces such as SMBus, SPI, and UART.

Feature Summary

• Integrates a high-speed 8051-compatible core with pipelined architecture for efficient instruction execution.
• Provides flexible I/O port assignment through on-chip Crossbar logic technology.
• Includes a full-speed non-invasive C2 system debug interface for development and testing.
• Features mixed-signal capabilities with a multi-channel 10-bit ADC and analog comparators.

Applications

• Industrial control systems requiring robust 8-bit processing
• Embedded sensor nodes utilizing onboard ADC and temperature sensors
• Battery-powered devices benefiting from low voltage operation
• General-purpose embedded applications needing serial communication interfaces

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches QFN-20 requirements. Ensure environmental ratings align with intended operational temperature ranges. Validate that OTP memory programming tools are compatible with the specific revision. Check for obsolescence status as availability may be limited.

Selection Notes

Select this model when a cost-effective 8-bit solution with integrated analog peripherals is required. Consider the 8 kB OTP limit for firmware size constraints. Evaluate the 25 MHz speed against real-time processing needs. Compare pin count and I/O flexibility with alternative packages if board space allows. Ensure development tools support the C2 interface for debugging.

Part Context

This component belongs to the C8051T63x family of fully integrated mixed-signal microcontrollers. These devices combine a standard 8051 CPU with extensive on-chip resources, reducing external component counts. The T-series typically denotes OTP memory variants, distinguishing them from Flash-based counterparts in the same product line.

Replacement Considerations

C8051T630-GM is a verified substitute within the same series offering identical electrical characteristics and functionality in a tube package instead of individual units.
