Migrating from ATV750B/BL PLD to ATF750C/CL
1. Introduction
The ATF750C/CL is a PLD from Atmel® in a 24- or 28-pin package with 24D or T-type
flip-flops, and it is an enhanced version of the well-known ATF750B/BL PLD. The
ATF750C/CL is reprogrammable using Atmel’s proven EEPROM-based technology
and is pin-to-pin, functionally, and JEDEC fuse-map wise compatible with the UV
EPROM-based ATV750B/BL.
In addition to all the features available in the ATV750B/BL, the ATF750C/CL also has
programmable pin-keeper circuits on all of its input and I/O pins, and the ATF750CL
has a much lower standby current (approximately 1 mA) than the ATV750BL. Moreover, package options offered for the ATF750C/CL are broader including RoHS
compliant (fully Green) packaging and TSSOP package type in addition to the traditional DIP, SOIC, PLCC, and LCC packages. For the ATF750C/CL in the LCC and
PLCC package types, there are also more V
ATV750B/BL in the same package types, which could help improve noise immunity of
the PLD.
The ATF750C is offered in Commercial, Industrial and Military temperature grades
while the ATF750CL is offered in Commercial and Industrial temperature grades.
Hence, only the ATF750C is offered in Military temperature grade but not the
ATF750CL. The ATF750C in Military temperature grade is also MIL-STD-883
compliant.
With the obsolescence of the ATV750B/BL family of devices, they are to be replaced
by the ATF750C/CL devices. This application note will provide details of the
ATV750B/BL-to-ATF750C/CL migration.

2. Cross Reference Tables
Table 2-1 lists the ATV750B/BL devices that are obsolete and the corresponding rec-
ommended ATF750C/CL replacements. For commercial and industrial applications, it
is recommended to use the ATF750C/CL in fully Green (RoHS) package types even
though some leaded packages are still available.

Notes: 1. The speed grade of the recommended replacement device is not the same as the speed grade
of the device being replaced.
2. The recommended replacement device is a Standard-Power device while the device being
replaced is a Low-Power (L) device.
