PAL22V10CF-7JC

Overview

The PAL22V10CF-7JC is a Cypress Semiconductor programmable logic device (PLD) based on the PAL architecture. It utilizes BICMOS technology and features 11 dedicated inputs and 10 I/O lines, totaling 21 logical inputs with one external clock input. The device operates within a commercial temperature range of 0°C to 70°C and supports a maximum clock frequency of 111 MHz. Key electrical parameters include a propagation delay of 7.5 ns, a maximum supply voltage of 5.25 V, and a package height of 4.57 mm. It contains 10 macrocells with variable product terms and shared input/clock capabilities.

Feature Summary

• PAL-type architecture with 10 macrocells and variable product terms
• BICMOS technology for high-speed operation up to 111 MHz
• Configuration: 11 dedicated inputs, 10 I/O lines, 1 external clock
• Commercial temperature range support (0°C to 70°C)

Applications

• High-speed state machine implementations
• Address decoding logic in computer systems
• Bus interface control circuits
• General-purpose combinatorial or registered logic design

Procurement Notes

Verify the package type upon ordering, as the suffix 'JC' typically denotes a Plastic Quad Flat Package (PQCC) variant, distinct from ceramic DIP options. Confirm RoHS compliance status, as older BICMOS PLDs may not meet current environmental directives. Ensure the specific speed grade (7.5 ns) matches the system timing requirements before procurement.

Selection Notes

Select this component when a reprogrammable PAL solution with moderate pin count is required. The 7.5 ns speed grade offers a balance between performance and power consumption for commercial applications. Consider the PQCC package if surface-mount assembly is preferred over through-hole DIP. Verify that the 11-input/10-I/O configuration fits the design constraints compared to variants with fixed outputs.

Part Context

This part belongs to the PAL22V10 family of second-generation programmable array logic devices. It shares architectural similarities with the PALC22V10 series but differs in technology (BICMOS vs. CMOS EPROM) and erasability. The PAL22V10CF-7JC represents a non-erasable OTP version optimized for cost-effective mass production in commercial electronics.

Replacement Considerations

Direct replacements include other PAL22V10 variants with compatible speed grades and pinouts, such as the PAL22V10C-7JCR for plastic packages. Cross-reference with generic GAL16V8 or GAL22V10 devices only if logic capacity and pin compatibility allow, though functionality may differ.
