PADAUK 5S-P-003C Microcontroller Programmer

Load your firmware onto supported PADAUK microcontrollers with the 5S-P-003C programmer. Designed for compatible OTP and MTP devices, it provides the programming step between developing your code and running it on the actual chip.

This listing includes the 5S-P-003C programmer and a SOT-23-to-DIP adapter for programming PMS150C-U06 microcontrollers in the SOT23-6 package. PMS150C microcontrollers are sold separately.

Key features

• Programs supported PADAUK OTP and MTP microcontrollers.
• Supports programming the popular, low-cost PADAUK PMS150C microcontroller.
• USB connection for loading programming files from your computer.
• Blank-check and verification functions to help check the programming process.
• Standalone programming after a file has been loaded, with the appropriate power supply connected.

Before ordering: Confirm support for your exact MCU and package in PADAUK’s compatibility table. Correct jumper settings and wiring are required. The included SOT-23-to-DIP adapter is for the PMS150C-U06 in SOT23-6; other MCU packages may require a different adapter or wiring arrangement. OTP chips cannot be erased and reused like reprogrammable devices.

Related microcontroller, sold separately. The following information describes the PMS150C chips you can develop with, not the 5S-P-003C programmer.

The PMS150C is a versatile, programmable 8-bit microcontroller. Your firmware defines how it responds to inputs, makes decisions and controls outputs, giving you a flexible foundation for automation, interactive electronics, lighting and motion control, and compact display interfaces.

At just USD $0.025 per chip in our separately sold USD $2.50, 100-piece chip bundle, before shipping and tax, it is well suited to cost-sensitive, high-volume embedded products where every cent matters, once the firmware is finalized.

Capabilities you can build on

• Input and decision-making: Read switches and digital sensor signals, apply logic and manage operating states in firmware.
• Timing and sequencing: Coordinate delays, timed actions and repeated control sequences with the on-chip timers.
• PWM and output control: Generate control signals for lighting and motion applications through suitable external drivers.
• User interaction: Combine button inputs, mode selection and status outputs to create responsive interfaces.
• Compact display interfaces: Drive text, numbers and simple graphics on the 0.32-inch OLED using our linked PMS150C library.

Design considerations

Select the capabilities your application needs and verify the firmware fits 1K-word program memory and 64 bytes of RAM. The U06 package provides four signal pins (PA3–PA6); PA5 has open-drain output. Use suitable power, interface and driver circuitry, and check the official PMS150C documentation for pin functions and electrical limits. Develop and test before one-time programming.

Building a tiny display project? Our open-source PMS150C 0.32-inch OLED library includes drawing routines and an application template for the PMS150C with the SSD1315 0.32-inch OLED, using PADAUK Mini-C and IDE 1.04C1. Choose only the features you need, check the build fits the chip’s memory, and test your wiring and firmware before programming OTP chips.
