TS87C51RB2-MIE

Microcontrollers Overview

The TS87C51RB2-MIE is an 8-bit microcontroller from the TS80C51Rx2 family, manufactured by Microchip Technology (formerly Atmel). It features a CMOS architecture with 32Kbytes of on-chip OTPROM and 256 bytes of internal RAM. The device supports a maximum clock frequency of 40 MHz at 5V and includes an X2 speed improvement capability. It utilizes a PDIP40 package and operates within a commercial temperature range.

Microcontrollers Feature Summary

• Compatible with 80C52 instruction set and pinout
• Includes Programmable Counter Array for capture/compare functions
• Features Dual Data Pointer registers for efficient memory access
• Supports hardware watchdog timer and multiple power control modes

Microcontrollers Applications

• Industrial control systems requiring high-speed processing
• Embedded applications utilizing multiprocessor communication via EUART
• Systems needing on-chip emulation capabilities through Once mode

Microcontrollers Procurement Notes

Verify that the ordering suffix corresponds to the specific package type and temperature grade required for your design. Confirm the OTPROM version matches the intended firmware deployment strategy. Ensure compatibility with existing 8051-based toolchains and development environments before finalizing procurement.

Microcontrollers Selection Notes

Select this component when an 8051-compatible core requires extended memory capacity beyond standard variants. The inclusion of the Programmable Counter Array makes it suitable for applications needing precise timing or pulse generation without external peripherals. Consider the X2 mode feature if higher throughput is necessary at lower crystal frequencies.

Microcontrollers Part Context

This part belongs to the TS80C51Rx2 series, which enhances the traditional 8051 architecture with expanded RAM, dual data pointers, and advanced timer capabilities. The TS87 variant specifically denotes the One-Time Programmable ROM option, distinguishing it from EPROM or ROMless counterparts within the same family.

Microcontrollers Replacement Considerations

Direct substitutes include other members of the TS80C51Rx2 family such as the TS87C51RC2 or TS87C51RD2, provided the package and memory size requirements are met. Verify pin compatibility and software register mapping when migrating between different memory configurations within the series.
