BS2PX24

Overview

The BS2PX24 is a BASIC Stamp module manufactured by Parallax Inc., based on the SX48W processor core. It features a 48-pin TQFP package with surface mount installation. The device operates within a voltage range of 3.15V to 3.45V and supports a maximum clock frequency of 25 MHz. Key specifications include 16 kB of ROM program memory, 512 kB of total memory capacity, and 64 programmable I/O pins. It integrates four 8-bit DACs and sixty-five timers, functioning as a complete microcontroller solution for embedded applications.

Feature Summary

• SX48W multicore processor architecture with 32-bit data bus
• Integrated 16 kB ROM and 512 kB memory space
• 64 programmable I/O pins with four 8-bit DACs
• Operating temperature range from -40°C to 125°C

Applications

• Embedded control systems requiring BASIC programming
• Industrial automation interfaces
• Sensor data acquisition modules

Procurement Notes

Verify component authenticity through authorized Parallax distributors. Confirm RoHS compliance status and check for AEC-Q100 automotive qualification if required for specific environmental conditions. Ensure proper ESD handling procedures are followed during storage and assembly due to the surface mount package type.

Selection Notes

Select the BS2PX24 when a dedicated BASIC interpreter environment is needed alongside high I/O density. Compare against the P2 series if higher processing speed or different instruction sets are required. Verify that the 25 MHz clock speed meets real-time processing requirements for the target application logic.

Part Context

This component belongs to the BASIC Stamp family, designed for simplified microcontroller programming. It utilizes the SX48W core, distinguishing it from standard Propeller chips by its focus on interpreted BASIC execution rather than direct parallel cog processing. It serves as a bridge between simple logic controllers and complex general-purpose microcontrollers.

Replacement Considerations

Direct pin-to-pin replacements may not exist due to unique firmware dependencies. Consider the P8X32A for similar I/O counts but different architecture, or the P2X8C4M64P for enhanced performance in the same package family. Software migration is typically required for any cross-family substitution.
