PIC16F15255T-I/STX

Microcontrollers Overview

The PIC16F15255T-I/STX is an 8-bit microcontroller from the PIC16F152 family, featuring a RISC core with up to 32 MHz operation. It includes 14 KB of Program Flash Memory and 1024 bytes of Data SRAM. The device provides 26 I/O pins with Peripheral Pin Select (PPS) capability. Key peripherals include a 10-bit ADC with 17 external channels, two CCP modules, two PWM outputs, one EUSART, and MSSP supporting SPI and I2C. It operates within a voltage range of 1.8V to 5.5V and supports industrial temperatures from -40°C to +85°C.

Microcontrollers Feature Summary

• Features a C compiler optimized RISC architecture with a 16-level deep hardware stack and automatic context saving for interrupts.
• Includes Memory Access Partition (MAP) to support data protection and bootloader applications by partitioning program memory.
• Integrates a Device Information Area (DIA) that stores Fixed Voltage Reference (FVR) offset values to improve ADC accuracy.
• Supports low-power consumption with Sleep mode current as low as 600 nA typical at 3V.

Microcontrollers Applications

• Cost-sensitive sensor applications
• Real-time control systems
• Bootloader implementations requiring memory partitioning

Microcontrollers Procurement Notes

Verify the ordering suffix 'T' indicates tape and reel packaging rather than tube. Confirm the '-I' suffix corresponds to the industrial temperature range (-40°C to +85°C). Ensure the '/STX' designation matches the specific SSOP-28 package variant required for your PCB layout. Cross-reference the datasheet revision to ensure compatibility with your development tools.

Microcontrollers Selection Notes

Select this model when 14 KB of flash memory is required, distinguishing it from the 7 KB PIC16F15254. Choose the T suffix for automated surface-mount assembly processes. Verify that the 10-bit ADC resolution and 17 external channels meet your analog input requirements. Consider the extended temperature option if operation above 85°C is necessary.

Microcontrollers Part Context

This component belongs to the PIC16F152 family of 8-bit microcontrollers. It shares architectural similarities with the PIC16F15254 but offers double the program memory. The family is designed for small form factor applications, available in various pin counts including 28-pin packages like SSOP and VQFN.

Microcontrollers FAQ

What is the function of the Memory Access Partition (MAP)?

The MAP feature allows the Program Flash Memory to be partitioned into Application, Boot, and Storage areas to support secure bootloaders and data protection.

How does the Device Information Area (DIA) benefit the ADC?

The DIA stores Factory-calibrated Fixed Voltage Reference (FVR) offset values, which helps improve the accuracy of the Analog-to-Digital Converter readings.
