PIC16F690-E/SS Übersicht
A microcontroller is a programmable integrated circuit that combines a processor core, program memory, data memory, I/O ports, and peripherals on one semiconductor die. The PIC16F690 belongs to the PIC16 family, a low-pin-count 8-bit MCU line intended for embedded control, sensing, communications, and small-system automation. Its Flash program memory supports in-system reprogramming, while the on-chip EEPROM provides nonvolatile data storage for calibration values, counters, configuration records, and other parameters that must survive power removal.
The verified sources identify 18 I/O pins, a 20 MHz clock speed, 12-bit ADC channels in the cross-reference data, and communication capabilities commonly associated with this PIC16 device. The -E/SS ordering code identifies the SSOP-20 package option. The SSOP package provides a compact surface-mount footprint for space-constrained assemblies while retaining a 20-pin device format.
PIC16F690-E/SS is suitable for compact control boards, sensor interfaces, low-power embedded controllers, communication modules, and industrial or consumer automation products. Designers should use the manufacturer datasheet and device-specific programming documentation to confirm oscillator configuration, peripheral multiplexing, ADC operating conditions, and electrical limits for the selected operating temperature grade.
For PCB layout, keep the microcontroller power pins and decoupling close to their package pins, route oscillator and high-impedance analog signals carefully, and validate programming and debug access before release. This page consolidates verified product, distributor, datasheet, pricing, and cross-reference information for engineering comparison and purchasing decisions.

Typische Anwendungen
PIC16F690-E/SS ist geeignet für 6 Anwendungs: Compact Sensor Interface Controller, Industrial Automation Controller, Battery-Powered Embedded Device, Serial Communication Hub, Consumer Appliance Controller, IoT Sensor Node.
Compact Sensor Interface Controller
PIC16F690-E/SS fits compact sensing products because it combines a 20 MHz 8-bit core, 18 I/O pins, a 12-channel 10-bit ADC, and serial communications in a 20-pin SSOP. It can acquire analog sensor values and transmit results through I2C, SPI, or USART, while 256 bytes of EEPROM preserves calibration or configuration data. The 2.0 V to 5.5 V family range also supports integration across low-voltage embedded platforms. Validate the ADC source impedance, sample time, reference voltage, and channel multiplexing in the exact datasheet.
Empfohlen
Industrial Automation Controller
The PIC16F690-E/SS is appropriate for small industrial control modules that need deterministic embedded logic, multiple digital inputs, serial device support, and nonvolatile local data. Its 18 I/O pins can be allocated among sensors, status indicators, relays, and service interfaces, while the 7 KB Flash memory supports a compact control program. The -E supply listing of 4.5 V to 5.5 V should be matched to the control board. Confirm industrial temperature, isolation, grounding, and regulatory requirements separately.
Empfohlen
Battery-Powered Embedded Device
PIC16F690-E/SS can serve as the control MCU in a battery-powered device because the PIC16F690 family uses nanoWart technology and supports a 2.0 V to 5.5 V family operating range. The device can control low-power sensors and communicate results through serial interfaces, reducing the need for a higher-power processor. Exact standby and active-current figures were not supplied, so battery sizing must use the manufacturer’s verified operating-current table rather than assumptions.
Empfohlen
Serial Communication Hub
The PIC16F690-E/SS can coordinate protocol conversion or device management because its verified feature set includes I2C, SPI, and USART alongside 18 I/O pins and 20 MHz operation. A hub design can use one interface toward a host and another toward sensors or actuators, with EEPROM storage for addresses and calibration data. Firmware and pin multiplexing must be planned together. The supplied data does not provide protocol timing guarantees for every operating condition, so verify them from the exact datasheet.
Empfohlen
Consumer Appliance Controller
The 20-pin PIC16F690-E/SS is useful in compact consumer products that need embedded control, serial communication, and limited analog monitoring without a larger MCU package. Its Flash memory allows firmware updates, EEPROM can retain user settings, and the ADC can monitor sensors such as temperature or level signals. Designers should confirm the -E grade voltage range, operating temperature, package footprint, and appliance-specific safety requirements. Use a local regulator and decoupling network sized for the MCU’s verified supply requirements.
Empfohlen
IoT Sensor Node
PIC16F690-E/SS can act as the local control and sensing MCU in a small IoT sensor node when the design needs low pin count, ADC channels, EEPROM, and serial connectivity. It can sample inputs, apply local thresholds, maintain configuration data, and forward events to a communications module. The 20-pin SSOP supports compact PCB layouts, while the 20 MHz clock provides timing margin for control tasks. The supplied data does not state radio functionality, so RF communication requires a separate module and system-level review.

Wichtigste Unterscheidungsmerkmale
- 7 KB Flash program memory with EEPROM data storage (vs. PIC16F690-I/SS)
- Compact 20-pin SSOP implementation (vs. PIC16F690-T/ P)
- Integrated mixed-signal and serial-control resources (vs. PIC16F690-I/SS)
- Grade-specific supply targeting (vs. PIC16F690-I/SS)
Designhinweise
Design the supply rail for the exact -E grade condition identified in the verified data: 4.5 V to 5.5 V for PIC16F690-E/SS. Place the required supply and ground connections directly at the device pins, and use local high-frequency decoupling close to the SSOP footprint. Validate brownout, startup, and maximum-voltage behavior against the exact Microchip datasheet rather than using the broader family-level 2.0 V to 5.5 V statement as a substitute for grade-level limits.
Use the manufacturer package drawing for the 20-pin SSOP land pattern and keep oscillator traces short and away from high-current switching nodes. Route I2C, SPI, and USART signals with controlled return paths, and place any external programming or debug interface where it does not compromise analog inputs. The supplied data identifies the package but does not provide the complete pin table, so do not infer exposed-pin or no-connect assignments from a generic SOIC footprint.
For analog measurements using the 12-channel 10-bit ADC, establish the source impedance, acquisition time, reference voltage, and sampling network from the exact datasheet. Keep analog inputs away from oscillator and digital return currents, and provide a stable reference arrangement if measurements require repeatable results. ADC accuracy depends on circuit impedance and layout, not only on the nominal 10-bit converter resolution.
Do not assume that every PIC16F690 order code is interchangeable merely because the family name is identical. Compare the -E and -I grade identifiers, package suffix, temperature range, voltage limits, qualification status, and programming documentation. A same-package listing can still be unsuitable if its electrical grade or device marking differs. Verify the final replacement with Microchip documentation and a prototype before production release.
Compliance-Informationen
The supplied verified data identifies the part as active but does not provide specific RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. These fields remain unknown rather than being inferred.
