STMicroelectronics ST92E163-EPB/US

Overview

ST92E163-EPB/US from STMicroelectronics is a dedicated programming board kit for ST9 microcontrollers with OTP and EPROM memory, supporting SDIP56 and QFP64 package variants of the ST92163 device. It connects via parallel port (LPT1/LPT2) to a Windows PC running STVP9 software, enabling read, program, verify, erase, and blank-check operations on target MCUs using ZIF sockets. Designed for low-volume development use, it supports Intel HEX and Motorola S19 file formats.

For engineers reviewing the ST92E163-EPB/US datasheet, ST92E163-EPB/US pinout, ST92E163-EPB/US application, or ST92E163-EPB/US equivalent, this board is selected for prototyping ST9-based embedded control systems requiring reliable, manual MCU programming without gang-programmer infrastructure.

Technical Context

The ST92E163-EPB/US implements hardware-level parallel-port interface logic to drive ST9 microcontroller programming voltages and timing sequences per ST's proprietary EPROM/OTP algorithm. It includes a configurable ZIF socket for SDIP56 packages and supports optional ISP mode only when paired with a compatible FLASH-based driver MCU (e.g., ST92F120), not natively on the ST92E163 itself.

Its operation relies entirely on host-controlled STVP9 firmware executing command sequences over the LPT port - no onboard microcontroller or firmware. Power is supplied externally (+15 VDC / 0.5 A) or via integrated supply, and ESD protection is absent, requiring static-safe handling per Appendix A.

FAQ

Does ST92E163-EPB/US support in-system programming (ISP) for the ST92163?

No. The ST92E163-EPB/US supports only ZIF-socket-based programming of OTP and EPROM versions of ST92163. ISP capability requires a FLASH-based ST9 device (e.g., ST92F120) used as a driver MCU on the same board, per Chapter 4 of the user manual - the ST92E163 itself lacks on-chip FLASH and cannot be programmed in situ.

What software is required to operate ST92E163-EPB/US?

STVP9 (ST Visual Programmer for ST9-EPB) is mandatory. It is a Windows-only graphical application included on the "MCU on CD" shipped with the kit. STVP9 handles file loading, memory mapping, voltage sequencing, and verification - no standalone or third-party tools are supported or validated.

Can ST92E163-EPB/US program QFP64-packaged ST92163 devices?

Yes, per Appendix B of the user manual, the ST92E163-EPB supports both SDIP56 and QFP64 packages of ST92163. However, the physical board layout varies by sales type - the /US variant corresponds to the SDIP56 configuration, and QFP64 support requires confirmation of the specific board revision and ZIF socket installed.

Is ST92E163-EPB/US compliant with modern PC interfaces like USB or PCIe?

No. It relies exclusively on legacy parallel port (LPT) connectivity. Modern PCs without native LPT headers require certified IEEE 1284-compliant parallel-port expansion cards - USB-to-parallel adapters are explicitly unsupported and will not function due to timing-critical bit-banging requirements.
