Microchip Doubles the Performance of the World's Smallest Microcontroller

CHANDLER, Ariz., — Microchip Technology Inc., announced two new members of the world’s smallest PIC10F microcontroller family – combining the new option of an onboard 8-bit analog-to-digital converter (ADC) with an 8-bit, Flash PIC® microcontroller in a 6-pin SOT-23 package. This functionality in an ultra-small form factor is well suited for an extremely wide range of space-constrained and low-cost applications. The PIC10F remains the first and only 6-pin microcontroller family in the world, and the increased performance and analog-to-digital converter serve to further expand non-traditional applications for digital intelligence.

“Since its introduction a year ago, the PIC10F family has seen tremendous market acceptance among both traditional and non-traditional microcontroller users,” said Steve Drehobl, vice president of Microchip’s Security, Microcontroller and Technology Development Division. “The fact that engineers have a microcontroller with an analog-to-digital converter that is the size of a surface-mount transistor, executing 2 million instructions per second, further expands the creative uses for PIC microcontrollers.”


The PIC10F 8-bit Flash microcontroller family adds two new members (PIC10F220 and PIC10F222) with a new 8-bit analog-to-digital converter, which compliments the comparator peripheral available on two of the four original family members. Standard features of the PIC10F microcontroller family include:

• Precision internal oscillator operating at up to 8 MHz with 33 instructions and two stack levels

• 1.125 ms Device Reset Timer (DRT)

• 256 to 512 instructions (x12-bit program words) of Flash program memory

• 16 bytes to 23 bytes of data RAM memory

• 25 mA source/sink current IO

• Low power (100 nA) sleep current

• Wide operating voltage range from 2- to 5.5-volts

• One 8-bit timer, and one watchdog timer

• In Circuit Serial Programming™ (ICSP™) technology for programming after placement on a board

• Power-on reset, and power-saving sleep mode


The new analog-to-digital converter, faster (8 MHz) internal oscillator and improved (1.125 ms) DRT make the new PIC10F220 and PIC10F222 well suited for battery-operated, power supply and property identification applications. However, the PIC10F family is well suited for any spaced-constrained application requiring low pin-count microcontrollers. Additionally, the combination of small form factor, high performance and extremely low cost is being readily adopted by applications not traditionally served by microcontrollers, including: Electronic Glue (bugs fixes, late changes and other stopgaps for ASICs and PCBs); Logic Control (replacement for delays, smart gates, signal conditioning, simple state machines, encoders/decoders, I/O expanders and small peripheral logic functions); Waveform Generation (replacement for 555 timers, pulse-width modulators (PWMs), remote control encoders, pulse generation, programmable frequency source, resistor-programmable oscillators); Mechatronics/Mechanical Functions (replacement for smart switches, mode selectors, remote I/Os, timers, LED flashers, other mechanical timers and switches); 4-bit Microcontroller Replacement; Intelligent Disposable Electronics (pregnancy testers, fireworks, dialysis monitoring (blood sugar), drug testers).
