ATF22V10C-10PI

Overview

The ATF22V10C-10PI is an Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features a high-performance CMOS architecture with 10 macrocells and 10 I/O pins in a 24-pin Plastic Dual Inline Package (PDIP). The device specifies a maximum pin-to-pin propagation delay of 10 ns, supporting a maximum operating frequency of 125 MHz. It operates on a 5 V power supply within the industrial temperature range of -40°C to +85°C.

Feature Summary

• High-speed performance with 10 ns maximum propagation delay
• Electrically erasable Flash memory technology for reprogramming
• Pin-controlled standby power mode reducing current to 10 µA typical
• Internal input and I/O pin-keeper circuits to maintain logic states

Applications

• Glue logic for 5.0V systems
• DMA control
• State machine control
• Graphics processing

Procurement Notes

Verify package type and speed grade against design requirements. Confirm RoHS compliance status if lead-free components are mandatory. Check for military-grade variants if extended temperature ranges are needed. Ensure programming tools support the specific JEDEC file format generated for this device.

Selection Notes

Select based on required propagation delay and I/O count. The PDIP package is suitable for through-hole mounting. Consider the C-10 speed grade for industrial applications requiring 10 ns delay. Verify compatibility with existing compiler software such as Synario or WINCUPL for design implementation.

Part Context

This component belongs to the ATF22V10C series of EEPLDs. It is backward-compatible with Atmel ATF22V10B(Q) and AT22V10(L) devices. The series offers various speed grades and package options to suit different system constraints while maintaining a standard pinout architecture.

FAQ

What is the function of the PD pin?

The PD pin enables a pin-controlled power-down mode. When held high, it reduces supply current significantly while latching all output data and internal logic states.

How does the device handle floating inputs?

Internal pin-keeper circuits hold inputs and I/O pins at their previous logic state when not driven externally, preventing indeterminate levels without requiring DC current.

What is the power-up reset behavior?

Registers reset to the low state during power-up. The clock must remain stable during the reset time, and input setup times must be met before driving the clock pin high.
