C8051T615-GM

Overview

The C8051T615-GM is a mixed-signal microcontroller from Silicon Labs, featuring an 8051-compatible core with up to 25 MIPS throughput at 25 MHz. It includes 16 kB of byte-programmable EPROM and 1280 bytes of internal data RAM. The device integrates a 10-bit ADC capable of 500 ksps, two voltage comparators, and a built-in temperature sensor. Digital peripherals include four 16-bit timers, a programmable counter array (PCA), enhanced UART, SMBus, and SPI interfaces. It operates on a supply voltage of 1.8 V to 3.6 V within a -40 °C to +85 °C temperature range.

Feature Summary

• Features a high-speed pipelined 8051 core executing most instructions in one or two system clocks for efficient processing.
• Integrates a 10-bit analog-to-digital converter with up to 500 ksps sampling rate and multiple input channels.
• Includes non-volatile byte-programmable EPROM memory allowing for in-circuit reprogramming and field upgrades.
• Provides flexible digital I/O configuration via a programmable crossbar decoder for simplified peripheral pin assignment.

Applications

• Industrial control systems requiring robust analog signal acquisition
• Battery-powered portable instruments utilizing low-voltage operation
• Data acquisition systems using the integrated high-speed ADC
• Embedded communication nodes employing UART, SMBus, or SPI interfaces

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the C8051T61x family utilizes distinct packages including QFN-28 and LQFP-32 variants. Confirm the exact memory capacity corresponds to the specific sub-model number within the T61x series before procurement. Ensure design compatibility with the specified operating voltage range and temperature specifications for the target application environment.

Selection Notes

Select this component when a fully integrated mixed-signal solution with EPROM storage is required for cost-sensitive applications. Consider the C8051T615-GM for designs needing high-speed analog conversion alongside standard digital communication interfaces. Evaluate the available GPIO count and timer resources against system requirements to ensure adequate peripheral allocation without external components.

Part Context

The C8051T615-GM belongs to the C8051T61x family of mixed-signal microcontrollers produced by Silicon Labs. This family is characterized by its byte-programmable EPROM technology, distinguishing it from Flash-based counterparts in the C8051F series. The devices are designed to offer a complete system-on-a-chip solution with extensive analog and digital peripherals integrated onto a single die.

Replacement Considerations

Direct replacements within the same footprint and code base include other members of the C8051T61x family such as the C8051T610, C8051T611, C8051T612, C8051T613, C8051T614, C8051T616, and C8051T617. These parts share identical pinouts and instruction sets but may differ in memory size or specific peripheral configurations.
