ATF20V8B-10JC

Overview

The ATF20V8B-10JC 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 within the commercial temperature range of 0°C to 70°C. It is housed in a 28-lead Plastic J-leaded Chip Carrier (PLCC) package, providing 18 logic inputs and 8 bi-directional I/Os.

Feature Summary

• Industry-standard architecture emulating many 24-pin PALs
• Reprogrammable Flash memory with 100 erase/write cycles
• CMOS and TTL compatible inputs and outputs
• Internal input and I/O pull-up resistors

Applications

• Direct replacement for 20R8 family devices
• Replacement for most 24-pin combinatorial PLDs
• Complex logic function realization in three configurable modes

Procurement Notes

Verify that the specific ordering suffix 'JC' corresponds to the Commercial temperature range (0°C to 70°C) and the 28-lead PLCC package as defined in the official Microchip ATF20V8B ordering information tables. Confirm RoHS compliance status if required, noting that Green Package options may carry different suffixes such as 'U'.

Selection Notes

Select this component when an electrically erasable solution is needed to replace legacy 24-pin PALs. Ensure the design requires 8 macrocells and fits within the 10 ns timing constraints. Consider power variants like ATF20V8BQ or ATF20V8BQL if lower active or standby current consumption is necessary for the application.

Part Context

This part belongs to the ATF20V8B series of high-speed EE PLDs. The series includes variants with different speed grades (-7, -10, -15, -25), power options (standard, Q, QL), and package types (PLCC, PDIP, SOIC, TSSOP). The 'J' indicates the PLCC package, while 'C' denotes the commercial temperature rating.

Replacement Considerations

The device can directly replace 20R8, 20RP8, 20R6, 20RP6, 20R4, and 20RP4 devices in registered mode. In complex mode, it replaces 20L8, 20H8, and 20P8. In simple mode, it substitutes various 14/16/18/20-pin PALs such as 14L8, 16L6, and 20L2.
