Applications
The PIC16F15256-I/SS is well suited for battery-powered sensor nodes, home automation controllers, and industrial I/O interface modules where an 8-bit microcontroller with ample Flash, dual PWM outputs, and multi-protocol serial communication is needed at low active current. Its 32 MHz maximum clock frequency and integrated 10-bit ADC make it a practical choice for embedded thermostat controllers, motor speed regulators using the dual CCP/PWM channels, and EUSART-based RS-232 or RS-485 protocol implementations. The SSOP-28 package and wide 1.8 V to 5.5 V supply range also enable drop-in compatibility with 3.3 V and 5 V system designs without level shifters.

Frequently Asked Questions
What is the Flash and RAM size of the PIC16F15256-I/SS, and how much firmware can it hold?
The PIC16F15256-I/SS contains 28 KB of Flash program memory and 2 KB of SRAM data memory, providing storage for approximately 14,000 14-bit PIC16 instructions and enough RAM for variable buffers, UART receive queues, and sensor data arrays in a typical embedded control application. This combination is sufficient for running a bare-metal control loop with MODBUS RTU protocol, 10-bit ADC averaging, and dual PWM motor control simultaneously without exceeding memory limits.
What is the maximum clock frequency of the PIC16F15256-I/SS, and at what voltage can it run at full speed?
The PIC16F15256-I/SS supports a maximum clock frequency of 32 MHz, achievable from a 2.3 V to 5.5 V supply using the internal oscillator or an external crystal. At the reduced voltage of 1.8 V, the device operates up to 16 MHz, which is sufficient for most sensor acquisition and communication tasks in battery-powered designs where supply voltage drops as the battery discharges below 2.3 V.
How does the Peripheral Pin Select (PPS) feature benefit PCB layout for the PIC16F15256-I/SS?
The PPS feature allows the EUSART TX/RX, SPI SCK/MOSI/MISO, I2C SDA/SCL, PWM outputs, and CCP capture inputs to be freely assigned to any of the digital I/O pins rather than fixed to specific package pins. This means PCB designers can route the UART signals to the most convenient pin locations for their connector layout, avoiding PCB traces that cross or detour around the SSOP-28 package, which is especially valuable on 2-layer PCBs with tight routing constraints.
What sleep current does the PIC16F15256-I/SS achieve with XLP technology, and how long can it run from a coin cell?
The PIC16F15256-I/SS XLP sleep mode achieves a typical sleep current below 1 µA at 3.3 V with the watchdog timer (WDT) enabled for periodic wake-up. A CR2032 coin cell with approximately 225 mAh capacity can sustain the device in sleep mode for over 25 years of calendar time, or operate a system that wakes every 1 second, samples a 10-bit ADC reading in under 1 ms at 1 mA active current, and returns to sleep for a total battery life exceeding 5 years.
When would you choose the PIC16F15256-I/SS over the PIC16F15225 for an SSOP-based embedded design?
Choose the PIC16F15256-I/SS over the PIC16F15225 when your firmware requires more than 14 KB of Flash program storage or more than 1 KB of SRAM, as the PIC16F15256 doubles the Flash to 28 KB and RAM to 2 KB compared to the PIC16F15225. If your application involves MODBUS RTU over EUSART, multiple display drive routines, or a USB HID emulation layer that exceeds 14 KB of compiled code, the PIC16F15256-I/SS in the same 28-pin SSOP footprint is a pin-compatible upgrade path without requiring a new PCB layout.
