Key Features

  • 8-bit PIC16 RISC core operating at up to 20 MHz (5 MIPS)
  • 1.5 KB on-chip Flash program memory with 100,000 write/erase endurance
  • 67 bytes SRAM for fast runtime variable storage
  • Three-channel 8-bit ADC for direct analog sensor measurement
  • Wide 2 V to 5.5 V supply voltage range for battery-powered operation
  • 14-pin TSSOP small outline package for space-constrained designs
  • Internal oscillator eliminates external crystal in many applications
  • Ultra-low sleep current for energy-efficient embedded control

Applications

The PIC16F506-I/ST is suited for low-cost sensor interfaces, simple motor speed control, and appliance timer circuits where a minimal 8-bit MCU with ADC capability is sufficient. Its 2 V minimum operating voltage supports alkaline and NiMH battery-powered designs without a boost converter. The 14-pin TSSOP package is commonly used in compact PCB assemblies for consumer electronics, HVAC sensors, and hobby robotics.

Frequently Asked Questions

How much program memory and RAM does the PIC16F506-I/ST provide for embedded firmware?

The PIC16F506-I/ST includes 1.5 KB (768 words) of Flash program memory with 100,000 write/erase endurance cycles and 67 bytes of SRAM for runtime variables. This memory footprint accommodates simple control loops, state machines, and ADC-based measurement routines typical in small embedded sensor and actuator applications.

Can PIC16F506-I/ST operate from a 2 V alkaline battery, and at what clock speed?

Yes. The PIC16F506-I/ST supports operation down to 2 V supply voltage at clock frequencies up to 4 MHz. This enables direct operation from two depleted 1.5 V alkaline cells or a single AA cell, extending battery life in remote sensors and disposable electronic devices without requiring an LDO regulator.

How many ADC channels are available on PIC16F506-I/ST, and what resolution do they provide?

The PIC16F506-I/ST integrates 3 ADC channels with 8-bit resolution, each capable of measuring 0 V to VDD analog inputs. At 5 V supply, this provides approximately 19.6 mV per bit, which is sufficient for reading temperature sensors, potentiometers, light sensors, and other resistive or voltage divider transducers commonly used in consumer appliances.

Is PIC16F506-I/ST a suitable replacement for older PIC12-series devices in legacy sensor control designs?

The PIC16F506-I/ST shares the same TSSOP-14 package and PIC16 core architecture with many PIC12 and PIC16 family members, simplifying pin-compatible upgrades. Its 3-channel ADC, 1.5 KB Flash, and 20 MHz clock exceed typical PIC12F508 capabilities (1 KB / 25 MHz), offering a path to more ADC channels and larger firmware without changing PCB layout.
