PIC16F570-I/SS - 8-Bit 20MHz Flash MCU with Analog | Microchip
料号： PIC16F570-I/SS ✓ 量产中PIC16F570-I/SS 概述
The PIC16F570-I/SS combines integrated Analog with the intelligence of a PIC microcontroller to create a low cost MCU suitable for a wide range of applications. Its on-board analog resources reduce the need for separate ADC, comparator, and signal-conditioning components. The MCU also supports 24 I/O, according to the product listing, allowing compact designs to connect discrete sensors, indicators, actuators, and communication interfaces while conserving board area.
Key device characteristics include 3 KB of Flash memory organized as 2K x 12, 64 bytes of RAM, a 200 ns instruction execution capability, and a compact instruction set of 33 single-word instructions. The industrial-temperature suffix identifies operation across the -40°C to +85°C range, while the SSOP suffix identifies the 28-lead surface-mount package used by the -I/SS orderable part. Flash programming allows in-circuit firmware updates and simplifies product revision control.
The device uses the baseline PIC16 8-bit RISC architecture, combining a compact instruction set with a straightforward register file and integrated peripherals. This architecture is useful for cost-sensitive controllers that execute control loops, monitor analog signals, and manage discrete outputs. Because the 3 KB Flash and 64 bytes of RAM are modest, firmware design should prioritize compact tables, interrupt-efficient polling, and avoidance of unnecessary library overhead.
Typical applications include industrial sensor and monitor modules, compact temperature or process transmitters, motor and actuator controllers, lighting-control boards, consumer appliances, and low-cost battery-operated instruments. The integrated ADC, dual op amps, and two comparators are particularly useful in designs where analog front-end conditioning, threshold detection, and MCU control are combined in one package.
When laying out the PCB, place the decoupling capacitor close to VDD and AVSS connections and route analog inputs away from switching nodes. Use the manufacturer pin-description table in the PIC16F570 data sheet before assigning PCB tracks, especially for analog, comparator, and programming pins.

典型应用
PIC16F570-I/SS 适用于 6 应用s: Industrial Sensor Monitoring, Temperature and Process Transmitters, Motor and Actuator Control, Lighting Control Boards, Battery-Operated Instruments, Appliance and Consumer Control.
Industrial Sensor Monitoring
The PIC16F570-I/SS fits compact sensor-monitoring modules because it combines a 20 MHz 8-bit core with an on-board ADC, dual op amps, and two comparators. A single MCU can digitize a sensor channel, condition the analog signal locally, compare it against thresholds, and control status indicators without a separate analog controller. Its 24 I/O support leaves external ports available for sensors, alarm outputs, and a serial interface, while the 3 KB Flash budget favors compact firmware and table-driven control logic.
推荐
Temperature and Process Transmitters
The PIC16F570-I/SS is appropriate for low-cost temperature and process transmitters where analog conditioning and digital output share a compact board. The integrated ADC handles sensor conversion, while the two op amps can buffer or amplify inputs and the comparators can provide threshold detection. Operating from a 2 V minimum supply at 8 MHz also supports battery-derived and low-voltage industrial designs. Firmware should stay within 64 bytes of RAM and 3 KB of Flash, favoring interrupt-efficient sampling and compact calibration tables.
推荐
Motor and Actuator Control
The PIC16F570-I/SS can serve as the controller in small motor, valve, or actuator modules where a 24 MHz-class clock is unnecessary but deterministic control timing is useful. Its 24 I/O provide connections for limit switches, position sensors, drive-enable signals, and status LEDs, while the comparator channels can monitor feedback signals against adjustable thresholds. The dual op amps can condition current-sense or sensor inputs before ADC conversion. Keep the firmware compact and isolate switching edges from the analog inputs to preserve measurement quality.
推荐
Lighting Control Boards
The PIC16F570-I/SS is well suited to compact LED and lighting-control boards that require local sequencing, button handling, and current monitoring. A 20 MHz Flash microcontroller provides enough execution speed for debouncing, dimming updates, and fault detection without requiring a larger MCU. The two comparators can monitor current-sense or fault signals, and the ADC can supervise a supply or temperature condition. Its 28-pin SSOP footprint supports dense boards, although the 3 KB program memory requires disciplined code organization for complex lighting tables.
推荐
Battery-Operated Instruments
The PIC16F570-I/SS works in low-power instruments because the manufacturer information identifies operation from a 2 V minimum supply at 8 MHz. This allows the controller to run directly from energy-harvesting or multi-cell-derived rails after appropriate regulation. Use the internal peripherals selectively, disable unused functions in firmware, and place the device into a low-power mode between measurements. The 64-byte RAM is adequate for short sample windows and compact calibration records but not for large data buffers.
推荐
Appliance and Consumer Control
The PIC16F570-I/SS provides a cost-effective control platform for appliances, timers, and compact consumer products that combine digital inputs with simple analog supervision. The 24 I/O can drive indicators, relays, keys, and small displays, while the ADC and comparators can check a tank level, temperature, or switch threshold. Flash programming simplifies firmware updates and product variants, and the 33-instruction PIC16 architecture keeps the code footprint predictable. Avoid heavyweight libraries when the 3 KB Flash capacity is the main design constraint.

关键差异点
- Integrated analog block reduces external component count （对比 PIC16F57-I/SS)
- Higher listed I/O count for compact control boards （对比 PIC16F57-I/SS)
- Defined industrial temperature grade （对比 PIC16F570-I/SP)
设计说明
Place the supply-decoupling capacitor as close as practical to the VDD pin and route the ground return directly to the device ground pins. Keep analog inputs, comparator inputs, and op-amp inputs away from high-current switching traces. Because this MCU combines analog and digital functions in one 28-pin package, a compact ground plane and short analog traces are more valuable than an elaborate external filtering stage.
The device is identified as operating from a 2 V minimum supply at 8 MHz. Do not assume that the 20 MHz maximum clock is available across every supply voltage; select the clock configuration from the manufacturer operating table and verify the regulator ripple at the VDD pin. Disable unused analog and digital functions in firmware when extending battery life, then measure the average current in the complete operating cycle.
The PIC16F570-I/SS has only 3 KB of Flash and 64 bytes of RAM, so oversized libraries, logging buffers, and duplicated lookup tables can exhaust the device quickly. Prefer compact state machines, shared conversion routines, and calculated calibration values. Before releasing firmware, review the map summary for RAM use and code space rather than assuming software behavior will scale as features are added.
合规信息
The -I/SS orderable part is identified as an industrial-temperature-grade PIC16 microcontroller. Specific RoHS, REACH, AEC-Q100, halogen-free, and conflict-minerals declarations are not stated in the product information, so their status remains unknown.
