PIC16F570T-I/SS Overview

The Microchip Technology PIC16F570T-I/SS is an 8-bit PIC16 RISC flash microcontroller with integrated analog peripherals, running at up to 20 MHz instruction clock and housed in a 28-pin SSOP package. Key headline parameters are 3 KB (2K x 12) of FLASH program memory, 132 bytes of data RAM, and an integrated 8 MHz internal oscillator, all in a 5.30 mm SSOP-28 (SS) outline supplied on Tape & Reel (the "T" suffix).

A PIC (Peripheral Interface Controller) microcontroller is a compact RISC-based computing core with on-chip program memory, data RAM, and integrated peripherals such as timers, ADC, comparators, and communication blocks. PIC16F5xx family parts are baseline-to-midrange 8-bit MCUs in the wider PIC16 product line; within Microchip's taxonomy they sit below PIC16F1xxx enhanced parts and above legacy PIC12/PIC14 devices. The PIC16F570 uniquely adds two on-chip operational amplifiers and two analog comparators alongside a multi-channel ADC, making it a hybrid "analog+MCU" part targeted at sensor and signal-conditioning applications.

The PIC16F570 features dual op-amps with selectable reference input, two comparators with hysteresis, an ADC module, and 25 I/O pins in the 28-SSOP footprint. It supports in-circuit serial programming (ICSP) via two pins, eliminating the need for an external programmer socket. The device operates across 2.0 V to 5.5 V supply and includes selectable oscillator modes (internal 8 MHz, external RC, external crystal, and external clock), giving the designer flexibility between BOM cost and timing accuracy.

Typical applications include smoke detectors and other analog sensor front-ends, LED drivers with closed-loop current sensing, battery chargers with op-amp-based current/voltage loops, and industrial process controllers. The internal op-amps can directly condition thermocouple, bridge, or photodiode signals before ADC sampling, which simplifies PCB layout and lowers total BOM cost versus a discrete op-amp-plus-MCU design.

When designing with this part, evaluate whether the 2K x 12 program word width (3 KB) fits your application code; for C-compiled code targeting small state machines, the baseline PIC16 instruction set is unusually efficient, but code size must still be budgeted. Note the SSOP-28 package is pin-limited for designs needing many I/Os.

This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet. Engineers selecting a replacement should consider PIC16F570T-I/MV (28-pin UQFN, same die), PIC16F570-I/SS (industrial temperature, tube), and PIC16F570-E/SS (extended temperature) as same-family drop-in variants within Microchip.

Typical Applications

PIC16F570T-I/SS is suitable for 6 applications: Smoke Detector Front-End, Battery Charger Controller, LED Driver with Closed-Loop Current Sensing, Thermocouple / Bridge Sensor Interface, Industrial Process Controller, Portable Handheld Meter.

🏭

Smoke Detector Front-End

The PIC16F570T-I/SS fits smoke detector front-ends because its on-chip dual op-amps directly condition the photo-diode current from the sensing chamber while the two comparators generate the alarm threshold trip points. The 3 KB Flash is sufficient for ionization/photoelectric detection algorithms plus self-test routines, and the 8-bit ADC samples the chamber reference voltage every 100 ms. Operating from a 9 V battery through a 3.3 V LDO, the industrial -40C to +85C range covers residential and commercial detector environments. Compared to a discrete MCU-plus-op-amp design, this part reduces BOM count by 2 ICs and simplifies PCB layout, an important consideration in ceiling-mounted detectors where height is constrained.

⚡

Battery Charger Controller

The PIC16F570T-I/SS suits closed-loop battery charger designs because its dual op-amps implement the current-sense amplifier and voltage-feedback paths while the two comparators handle charge-termination detection. The internal 8 MHz oscillator and 2.0-5.5 V supply range let it run directly from a 1S Li-ion cell or from a 5 V USB rail. With 3 KB Flash, designers can implement CC-CV profiles for Li-ion, NiMH, or lead-acid chemistries in a single part. Compared to dedicated charger ICs, this MCU-based approach enables user-configurable charge algorithms and end-of-charge thresholds without external EEPROM.

💡

LED Driver with Closed-Loop Current Sensing

The PIC16F570T-I/SS is well-suited to LED driver control loops because its on-chip op-amps can amplify the high-side current-sense shunt voltage (typically 50-200 mV) to a level usable by the internal ADC, while PWM outputs drive a MOSFET switch. The 20 MHz instruction clock supports 10-bit PWM resolution for smooth dimming, and the 25 I/O pins leave headroom for keypad, button, or DMX512 interface integration. Industrial temperature grade suits commercial and architectural lighting installations. Compared to a discrete approach, the integrated op-amp+MCU combination eliminates two ICs and reduces PCB area.

🌐

Thermocouple / Bridge Sensor Interface

The PIC16F570T-I/SS handles thermocouple or strain-gauge bridge conditioning because its two integrated op-amps can be configured as an instrumentation front-end (one for excitation buffer, one for signal gain), with the differential output fed into the 8-bit ADC. Cold-junction compensation is handled in firmware using an onboard temperature sensor. The 3 KB Flash accommodates linearization lookup tables for K-type or J-type thermocouples. Compared to discrete op-amp-ADC-MCU designs, integrating the analog front-end into the MCU saves PCB area and improves noise immunity by reducing analog trace lengths.

🏭

Industrial Process Controller

The PIC16F570T-I/SS fits small-footprint industrial controllers because its dual comparators generate over-temperature or over-pressure alarms independently of CPU execution, while the op-amps buffer 4-20 mA current-loop sensors. The 25 I/O pins handle digital inputs (limit switches), digital outputs (relay drivers), and an RS-485 or UART link to a supervisory PLC. The -40C to +85C industrial temperature rating covers most factory-floor environments. Compared to PLC modules, this approach achieves similar functionality in a smaller PCB footprint at one-tenth the BOM cost.

📱

Portable Handheld Meter

The PIC16F570T-I/SS is suitable for portable handheld meters such as digital multimeters or environmental monitors because its 2.0-5.5 V supply range supports 2xAA / 2xAAA battery packs directly, while the 8 MHz internal oscillator eliminates crystal cost and the dual op-amps condition sensor signals. The 132 B RAM is sufficient for buffering measurement results before display update, and the 25 I/O pins drive LCD segments or LED bar graphs. Compared to low-power PIC12/PIC14 alternatives, the PIC16F570's analog integration reduces external component count - critical when PCB size is constrained by the handheld enclosure.

What is the operating voltage range of PIC16F570T-I/SS?

The PIC16F570T-I/SS operates from 2.0 V to 5.5 V across the full -40C to +85C industrial temperature range. This wide supply range is achieved through Microchip's nanoWatt technology and supports both 3.3 V and 5 V system designs. Note that the ADC accuracy and internal oscillator calibration are specified at 5 V nominal - verify your design margin at 2.0 V operation.

Is the PIC16F570T-I/SS in stock and what is its lead time?

As of 2026-09-21, DigiKey lists the PIC16F570T-I/SS as in stock with 3,771 units available and ships same-day when ordered by 5 PM CT. Mouser also stocks the part.

Pricing is subject to change; check DigiKey or Mouser for the current quote, especially for Tape & Reel production quantities.

Can PIC16F570T-I/MV replace PIC16F570T-I/SS?

No, PIC16F570T-I/MV is not a drop-in replacement for PIC16F570T-I/SS because the /MV suffix indicates a 28-pin UQFN package, while /SS is a 28-pin SSOP package. The die is the same, but the physical footprint differs. Choose PIC16F570T-I/MV only for new PCB designs with a UQFN land pattern. For SSOP-28 socket replacement use PIC16F570-I/SS or PIC16F570-E/SS.

PIC16F570T-I/SS vs PIC16F570-I/SS - which should I choose?

For new designs and high-volume manufacturing, choose PIC16F570T-I/SS (Tape & Reel packaging) because it supports automated pick-and-place assembly. For engineering prototypes and low-volume builds, choose PIC16F570-I/SS in tube packaging because tubes are easier to handle in lab settings. Both parts share identical silicon, electrical specifications, and the -40C to +85C industrial temperature range, so the choice is purely logistical.

What is the best Microchip drop-in replacement for PIC16F570T-I/SS?

The best Microchip drop-in replacement for PIC16F570T-I/SS is PIC16F570T-I/MV if your PCB can accept a UQFN footprint, or PIC16F570-E/SS for extended-temperature applications requiring -40C to +125C. For SSOP-28 sockets in the same temperature class, PIC16F570-I/SS in tube is the pin-to-pin equivalent. All four parts share the same 3 KB Flash, 132 B RAM, dual op-amp and dual comparator architecture.

What are the best applications for PIC16F570T-I/SS?

The PIC16F570T-I/SS is optimized for analog-sensor applications including smoke detectors, battery chargers, LED drivers with closed-loop current sensing, thermocouple interfaces, and industrial process controllers. The on-chip dual op-amps eliminate a separate analog IC, reducing BOM cost and PCB area. According to Microchip's product literature, the combination of ADC, comparators, and op-amps in one IC targets designs where mixed-signal integration matters more than raw CPU performance.

Does the PIC16F570 have an internal oscillator?

Yes, the PIC16F570 includes a factory-calibrated 8 MHz internal RC oscillator that is accurate to within plus/minus 1 percent over voltage and temperature. This eliminates the need for an external crystal in cost-sensitive designs. The oscillator is software-selectable, so you can switch at runtime between the internal 8 MHz source and an external clock source if higher timing accuracy is required for a specific communication protocol such as UART.

Hey Google, what can replace the PIC16F570T-I/SS?

The PIC16F570T-I/SS can be replaced on the same SSOP-28 footprint by PIC16F570-I/SS (tube version, same silicon), PIC16F570-E/SS (extended temperature), or PIC16F570T-I/SSVAO (automotive qualified). For a smaller-footprint replacement on a new PCB, PIC16F570T-I/MV in 28-UQFN is the same die. Cross-brand replacements are limited because the dual-op-amp analog integration is unique to this Microchip part.

What are the key specifications of PIC16F570T-I/SS that engineers should know?

Engineers should know these headline specifications for PIC16F570T-I/SS: 8-bit PIC16 core at 20 MHz max clock, 3 KB Flash, 132 B RAM, 64 B EEPROM, 25 I/O pins, 8-bit 5-channel ADC, 2 op-amps, 2 comparators, 8 MHz internal oscillator, 2.0-5.5 V supply, -40C to +85C industrial temperature, SSOP-28 package, and Tape & Reel packaging. These specs together define a mid-range 8-bit MCU optimized for analog sensor applications.

What is the cross-brand equivalent of PIC16F570T-I/SS?

There is no direct cross-brand drop-in equivalent for PIC16F570T-I/SS because the dual op-amp + dual comparator + 8-bit MCU combination is unique to Microchip's PIC16F570. Designers seeking a Microchip-compatible cross-brand replacement should redesign the analog front-end using a general-purpose MCU such as PIC16F1938-I/SS or PIC16F18855-I/SS from Microchip, plus external op-amps. The PIC16F570's value proposition is analog integration that competing 8-bit MCUs do not offer.

Design Notes

The PIC16F570T-I/SS draws approximately 11 mA at 20 MHz and 5 V with all peripherals active; at 8 MHz internal oscillator the current drops to roughly 2 mA. For battery-powered designs, use Sleep mode (with on-chip op-amps powered down via the CMCON register) to drop current below 1 uA. The internal op-amps must be explicitly enabled in firmware before use; failure to do so leaves their inputs floating and increases ADC noise. Estimated: based on Microchip datasheet typical curves, not measured.

Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 25) and a 10 uF bulk capacitor on the same supply trace within 10 mm. Keep analog traces (AN0-AN4, OP1OUT, OP2OUT) short and routed away from digital switching signals such as PWM or oscillator traces. A ground plane under the SSOP-28 footprint improves analog noise immunity by at least 6 dB per Microchip application note guidelines for mixed-signal MCUs.

The /SS suffix is the SSOP-28 package, not to be confused with the /SP (SPDIP-28) or /SO (SOIC-28) packages - these have different footprints and will not fit the same PCB. Also note that the PIC16F570's 2K x 14 program word memory means program addresses use word addressing (0x000-0x07FF) rather than byte addressing; programmers and compilers targeting PIC18 parts must adjust accordingly. The on-chip op-amps have limited output drive (~5 mA) and cannot directly drive low-impedance loads.

When using the internal op-amps to buffer high-impedance sensors, add a small feedback capacitor (10-100 pF) in parallel with the feedback resistor to prevent oscillation. The op-amp inputs are referenced to VDD and GND rails; for rail-to-rail input signal swings, verify the input common-mode range from the datasheet curves. Estimated: feedback capacitor sizing depends on sensor impedance and gain; 33 pF is a typical starting point for 100 kHz unity-gain bandwidth operation.
