TS80L188EC13

Overview

The TS80L188EC13 is a 16-bit microprocessor manufactured by Intel, operating at a maximum clock frequency of 13 MHz. It utilizes CMOS technology and features a 20-bit address bus with an 8-bit external data bus. The component is housed in a 100-pin Plastic Quad Flat Pack (PQFP) package. Key integrated peripherals include a DRAM refresh controller, three programmable timers, and emulation hardware support. It supports low-power modes and is compatible with the 80C187 numeric processor extension.

Feature Summary

• Integrates a DRAM refresh controller for memory management
• Includes three programmable timers for system control
• Supports emulation hardware for development debugging
• Features low-power operation modes

Applications

• Embedded systems requiring 16-bit processing
• Industrial control applications
• Systems utilizing 80C187 numeric extensions

Procurement Notes

Verify the manufacturer designation, as this part is historically associated with Intel rather than Altera. Confirm the specific package variant (PQFP vs SQFP) matches the design requirements. Ensure compliance with RoHS standards if required, as older CMOS variants may not be compliant. Cross-reference the speed grade to confirm the 13 MHz rating aligns with system timing constraints.

Selection Notes

Select this component for legacy embedded designs requiring 16-bit architecture with integrated peripheral functions. Consider the 13 MHz speed limit when designing clock circuits. Verify compatibility with existing 80C186/188 software environments. Evaluate power consumption requirements against the available low-power modes. Ensure the 100-pin QFP footprint fits the PCB layout constraints.

Part Context

This processor belongs to the 80C186/188 family of high-integration embedded processors. It is a member of the 186 instruction set architecture lineage. The 'L' suffix typically denotes low-voltage or specific speed binning within the Intel product line. It serves as a bridge between standard microprocessors and highly integrated microcontrollers.

Replacement Considerations

Compatible substitutes include the SB80L188EC13 and other variants within the 80C188EC series such as the 80C188EC20 or 80C188EC25, provided speed and voltage requirements are met.
