STMicroelectronics ST62E2XC-EPB/110

Overview

ST62E2XC-EPB/110 from STMicroelectronics is a dedicated EPROM programming board for ST62E0x/T0x/E1x/T1x/E2x/T2x microcontrollers, supporting in-situ programming via parallel or 25-pin serial PC interface, standalone key-operated operation, and full Read/Program/Verify/Blank-check functionality with included WINEE software on CD-ROM.

For engineers reviewing the ST62E2XC-EPB/110 datasheet, ST62E2XC-EPB/110 pinout, ST62E2XC-EPB/110 application, or ST62E2XC-EPB/110 equivalent, this board enables single-site, socket-based EPROM programming of legacy ST6 microcontrollers in production, repair, and development environments where OTP/EPROM reprogramming capability is required without full-scale production programmers.

Technical Context

The ST62E2XC-EPB/110 implements dedicated hardware-level address/data/control signal generation for ST6 EPROM devices, including VPP programming voltage switching (12.5 V), precise timing control for EPROM write cycles, and automatic device detection for ST62E2x/T2x families. It supports both parallel (8-bit data bus + control lines) and asynchronous serial (RS-232 level) host interfaces.

Standalone mode uses onboard firmware to execute preconfigured programming sequences triggered by front-panel keys, while PC-connected mode relies on ST's Windows-based WINEE software for full scriptable control, memory dump import/export, and batch programming - with no embedded microcontroller or user-programmable logic on the board itself.

Key Specifications

Manufacturer

STMicroelectronics is a global semiconductor manufacturer headquartered in Geneva, Switzerland, specializing in microcontrollers, power management, sensors, and automotive ICs with broad industrial and consumer reach.

This part belongs to the ST6-EPB family of dedicated EPROM programming boards, designed specifically to enable field and bench-level reprogramming of obsolete ST6-series microcontrollers using EPROM or OTP memory technology.

FAQ

Is ST62E2XC-EPB/110 compatible with ST62E3x or ST62E4x microcontrollers?

No. ST62E2XC-EPB/110 is physically and electrically configured only for ST62E2x/T2x devices. ST62E3x requires ST62E3X-EPB, and ST62E4x requires ST62E4XB-EPB - each has unique socket layout, VPP timing, and address decoding logic per device family.

Does ST62E2XC-EPB/110 require external power, and what are the specifications?

Yes. It requires an external 12 V DC power adapter (included), delivering ≥1.5 A. Internally, it generates regulated 5 V for logic and precisely controlled 12.5 V for EPROM programming pulses - no USB or host-powered operation is supported.

Can ST62E2XC-EPB/110 program modern Flash-based ST microcontrollers?

No. It is exclusively designed for EPROM/OTP variants of the ST6 architecture (e.g., ST62E25C, ST62T25). It lacks the voltage sequencing, clocking, and protocol support needed for STM8 or ARM-based Flash devices - no firmware or hardware upgrade path exists.

What operating systems support the included WINEE software?

The supplied WINEE software runs on Windows XP and Windows 7 (32-bit only). It is not compatible with Windows 10/11 or any 64-bit OS without compatibility mode and signed driver exemptions - no official macOS or Linux version was released.
