BS2E-IC

Overview

The Parallax BS2E-IC is an integrated circuit module based on the Microchip PIC16C57 microcontroller, designed for use with the BASIC Stamp development environment. It features a 2048-byte EEPROM for program storage and operates within a voltage range of 2.5 V to 5.5 V. The component supports I2C communication interfaces with a maximum clock frequency of 400 kHz and includes built-in serial programming capabilities. It is housed in a DIP package suitable for through-hole mounting.

Feature Summary

• Integrated PIC16C57 core with 2048-byte EEPROM
• Supports BASIC Stamp (BS2) instruction set
• I2C interface with 400 kHz max clock speed
• Operating voltage range of 2.5 V to 5.5 V

Applications

• BASIC Stamp educational development kits
• Embedded control systems requiring serial programming
• Industrial automation modules using I2C bus
• Robotics platforms needing compact logic control

Procurement Notes

Verify component authenticity as the BS2E-IC may be discontinued or limited in supply. Confirm package type and pinout compatibility with existing motherboards. Check for moisture sensitivity labeling if storage conditions are uncontrolled. Ensure replacement parts match the original electrical specifications and firmware support requirements.

Selection Notes

Select this IC when BASIC Stamp compatibility is required for rapid prototyping. Consider the 2048-byte memory limit for complex applications. Verify that the host system provides stable 5 V power or level shifting for 3.3 V operation. Ensure the design accommodates the DIP package footprint and serial programming header connections.

Part Context

The BS2E-IC serves as the central processing unit for Parallax BASIC Stamp modules. It bridges high-level BASIC commands with low-level PIC microcontroller operations. This component was widely used in educational robotics and simple embedded projects before being superseded by newer Propeller and Arduino-based solutions.

Replacement Considerations

Direct pin-to-pin replacements are not publicly documented for the BS2E-IC due to its proprietary BASIC Stamp firmware integration. Alternative designs typically require migrating to standard PIC microcontrollers with custom bootloader implementations or switching to compatible development boards from other manufacturers.
