ATF20V8BQL-15JC

Overview

The ATF20V8BQL-15JC is a high-performance electrically erasable programmable logic device (EE PLD) manufactured by Microchip Technology. It features 8 macrocells and supports up to 8 I/O pins within a 28-lead Plastic J-leaded Chip Carrier (PLCC) package. The component operates at a maximum propagation delay of 15 ns with a clock frequency up to 62 MHz in no-feedback mode. It utilizes advanced Flash technology for reprogrammability, offering 20-year data retention and 100 erase/write cycles. The device functions on a 5V supply and is rated for commercial temperature ranges from 0°C to 70°C.

Feature Summary

• Industry-standard architecture emulating many 24-pin PALs
• Advanced Flash technology enabling full reprogrammability
• CMOS and TTL compatible inputs and outputs
• Internal input and I/O pull-up resistors

Applications

• Direct replacement for 20R8 family devices
• Combinatorial logic applications requiring output enable control
• State machine initialization circuits

Procurement Notes

Verify the ordering suffix 'JC' corresponds to the 28-lead PLCC package and Commercial temperature range (0°C to 70°C). Confirm that the -15 speed grade meets the system timing requirements of 15 ns maximum pin-to-pin delay. Ensure the design accounts for the specific power consumption characteristics of the BQL variant compared to standard or low-power B/BQ versions.

Selection Notes

Select this part when an industry-standard 24-pin PLD footprint is required but surface-mount packaging is preferred via PLCC. The BQL variant offers lower active current (20 mA typical) than the standard B version (55 mA typical), making it suitable for power-constrained designs. Verify that the 15 ns speed grade satisfies the maximum clock period constraints of the target application logic.

Part Context

This component belongs to the ATF20V8B family of high-speed EE PLDs. The family includes variants with different speed grades (-7, -10, -15, -25) and power options (standard, Q, QL). The ATF20V8BQL specifically denotes the low-power variant with optimized standby and active currents while maintaining the 15 ns performance tier.

Replacement Considerations

The ATF20V8BQL-15JC can directly replace 20R8, 20RP8, 20R6, 20RP6, 20R4, and 20RP4 registered devices. It also serves as a drop-in replacement for most 24-pin combinatorial PLDs such as 20L8, 20H8, and 20P8 when configured in Complex Mode.
