Product details

Overview

C8051T610 from Silicon Laboratories is a mixed-signal, byte-programmable EPROM microcontroller featuring an enhanced 8051 core, 10-bit ADC (500 ksps), on-chip LDO regulator, and integrated temperature sensor. It delivers up to 25 MIPS at 25 MHz, supports 1.8–3.6 V operation, and targets low-power embedded sensing and control in industrial monitoring systems.

For engineers reviewing the C8051T610 datasheet, C8051T610 pinout, C8051T610 application, or C8051T610 equivalent, key selection criteria include its 32-pin LQFP package, 16 kB EPROM + 1280 B RAM memory map, internal 24.5 MHz oscillator with ±2% accuracy, and hardware UART/SMBus/SPI peripherals for sensor interface consolidation.

Technical Context

The C8051T610 implements a pipelined CIP-51 8051-compatible core executing 70% of instructions in 1–2 system clocks, enabling deterministic real-time response. Its analog subsystem integrates a 10-bit ADC with up to 21 external inputs, programmable VREF sourcing (external pin, internal regulator, or VDD), and built-in temperature sensor calibrated for ±1.5 °C accuracy over –40 to +85 °C.

Digital I/O includes 29-port crossbar-mapped GPIO with high sink current, four 16-bit timers, a 16-bit programmable counter array (PCA) supporting five capture/compare modules and PWM generation, plus dedicated hardware serial interfaces: UART0, SMBus, and enhanced SPI0 - all configurable via SFRs without CPU overhead.

Equivalent & Alternatives

The following parts are listed as comparable options for similar mixed-signal microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
C8051F310	Same 8051 core, but 8 kB flash (not EPROM), no integrated temperature sensor, 28-pin QFN package	Lacks on-die temperature sensing and 16 kB program memory; suitable for cost-sensitive, lower-feature designs	Select when flash reprogrammability is required and temperature sensing is handled externally
EFM8BB10F8G	Silicon Labs EFM8 Busy Bee family: 8 kB flash, 512 B RAM, 12-bit ADC (200 ksps), same 24.5 MHz oscillator accuracy	Higher-resolution ADC but lower sample rate; lacks EPROM non-volatility and comparator-as-reset capability	Prefer for new designs requiring modern flash architecture and lower active current, accepting trade-offs in analog feature set

Compared with C8051T610, the C8051F310 offers flash-based field updates but omits temperature sensing and half the program memory, while the EFM8BB10F8G provides higher ADC resolution and lower power but sacrifices EPROM reliability and comparator-driven reset functionality critical in safety-monitored systems.

FAQ

What is the maximum ADC sampling rate supported by the C8051T610?

The C8051T610 supports a maximum ADC sampling rate of 500 ksps in its 10-bit mode. This performance is achievable with the internal 24.5 MHz oscillator and proper configuration of the ADC conversion trigger source and clock prescaler. The C8051T610 ADC achieves this rate while maintaining full 10-bit resolution and linearity across its specified operating range.

Does the C8051T610 include an integrated temperature sensor?

Yes, the C8051T610 includes a factory-calibrated on-die temperature sensor with ±1.5 °C accuracy over the full –40 °C to +85 °C industrial temperature range. The sensor output connects directly to ADC0 channel 7 and is accessible via the TEMP pin; no external components are required for basic thermal monitoring in the C8051T610.

What package type is used for the C8051T610?

The C8051T610 is exclusively offered in a 32-pin LQFP package (7 × 7 mm, 0.8 mm pitch). This package is distinct from other variants in the C8051T6xx family - such as the C8051T611 (28-pin QFN) or C8051T616 (24-pin QFN) - and is mechanically and electrically optimized for the C8051T610's full I/O and analog peripheral count.

Can the C8051T610 operate without an external crystal?

Yes, the C8051T610 can operate without an external crystal using its internal 24.5 MHz precision oscillator, which maintains ±2% accuracy across voltage and temperature. This capability enables crystal-less UART communication at standard baud rates (e.g., 9600, 115200) and reduces BOM cost and board space - a verified feature of the C8051T610 per its datasheet revision 1.1.

Is the C8051T610 still recommended for new designs?

No - the C8051T610 is marked "Not Recommended for New Designs" in Silicon Labs' official documentation (Rev 1.1, June 2011). While fully functional and supported for existing production, new projects should consider modern alternatives like the EFM8BB series for flash-based flexibility, lower power, and extended lifecycle support. The C8051T610 remains available for legacy continuity and repair scenarios.
