ATF20V8B-10JI

Overview

The ATF20V8B-10JI is a high-performance Electrically Erasable Programmable Logic Device (EE PLD) manufactured by Microchip Technology. It utilizes CMOS Flash memory technology and features 8 macrocells with a maximum pin-to-pin propagation delay of 10 ns. The device operates at a nominal 5V supply voltage and supports Industrial temperature ranges from -40°C to +85V. It is housed in a 28-lead Plastic J-leaded Chip Carrier (PLCC) package, providing 18 dedicated inputs and 8 bi-directional I/Os.

Feature Summary

• Industry-standard architecture emulating many 24-pin PALs
• High-speed Electrically-erasable Flash technology with 7.5 ns to 25 ns speed grades
• CMOS and TTL compatible inputs and outputs with internal pull-up resistors
• Reprogrammable with 100 erase/write cycles and 20-year data retention

Applications

• Direct replacement for 20R8 family and most 24-pin combinatorial PLDs
• Complex logic function realization using registered, complex, or simple modes
• State machine initialization with power-up reset feature

Procurement Notes

Verify the ordering code matches the required speed grade (-10) and industrial temperature range (-I). Confirm the package type is 28-lead PLCC (28J). Ensure compatibility with standard PLD programmers for programming and erasing operations.

Selection Notes

Select this part for applications requiring direct replacement of 24-pin PAL devices. Choose the -10 speed grade for 10 ns max delay. Consider lower power variants like ATF20V8BQ or ATF20V8BQL if power consumption is a critical constraint.

Part Context

The ATF20V8B series includes variants with different speed grades (-7, -10, -15, -25) and power options (standard, Q, QL). The -10JI variant specifically denotes the 10 ns speed grade, Industrial temperature range, and 28-lead PLCC package.

Replacement Considerations

Can directly replace 20R8, 20RP8, 20R6, 20RP6, 20R4, and 20RP4 devices in registered mode. Can emulate 20L8, 20H8, 20P8 in complex mode. Can emulate 14L8, 14H8, 14P8, 16L6, 18H6, 16P6, 18L4, 18H4, 18P4, 20L2, 20H2, 20P2 in simple mode.
