I love short, sharp, and focused product releases that tell me what I want to know in as concise a manner as possible. Based on this, the following release from Silicon Labs is just about perfect as far as I am concerned:
Silicon Labs’ new *C8051F39x/37x 8-bit microcontrollers (MCUs)* deliver best-in-class temperature sensing accuracy and a high level of analog integration, making them ideal a wide range of consumer, industrial and communication applications, including optical transceiver modules, motor control and sensor interfaces. The MCU family’s exceptional integration eliminates the need for external components, further reducing bill-of-materials (BOM) cost and PCB footprint.
On-chip temperature sensor
High integration in a tiny 4 mm x 4 mm package
- ±2 °C accuracy through an extended temperature range (up to 105 °C)
- Improves temperature compensation routines (better end-product reliability)
- Factory calibration not required (reduces manufacturing costs)
Fast 8051 microcontroller core with four interrupt priority levels
- Ideal for space-constrained applications (30% smaller than competing solutions)
- Eliminates need for external components such as a temperature sensor, a crystal, a differential ADC, a voltage reference and two DACs (reduces BOM)
- 512 bytes of byte-programmable EEPROM for up to 1M write/erase cycles (F37x only)

- 2.5 times faster CPU performance (up to 50 MIPS) than competing devices
- Finer resolution PWM offers ability to execute more complex algorithms (greater range of motor speeds and higher efficiency in motor control applications)
- Interrupt priorities enable fast interrupt handling for real-time applications
