CS82C54-1096

Overview

The CS82C54-1096 is a CMOS programmable interval timer manufactured by Renesas Electronics Corporation. It integrates three independent 16-bit counters capable of handling clock input frequencies up to 10 MHz. The device operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum propagation delay of 100 ns. It is housed in a 28-pin PLCC package with surface mount installation. The component supports an industrial temperature range from -40°C to +85°C and provides CMOS outputs with high-level and low-level output currents of 2.5 mA.

Procurement Notes

The CS82C54-1096 is listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verification of current lifecycle status and sourcing channels is required before procurement planning.

Selection Notes

Select the CS82C54-1096 for designs requiring a 10 MHz programmable timer in a 28-PLCC package. Ensure the system operates within the 4.5 V to 5.5 V supply range and accommodates the -40°C to +85°C temperature environment. Verify compatibility with existing NMOS 8254 software if migrating from older components.

Part Context

This component belongs to the 82C54 series of CMOS programmable timers. It serves as a high-performance replacement for NMOS 8253/8254 devices, offering enhanced speed and lower power consumption while maintaining functional compatibility with industry-standard microprocessors such as the Intel 80C86 and 80C286.

Replacement Considerations

Direct pin-compatible alternatives within the same family include the IS82C54-10 (10 MHz) and CS82C54Z96 (8 MHz). Note that package variations exist; ensure the substitute matches the 28-PLCC form factor.
