MAX 7000B Programmable Logic Device Data Sheet
Power
Sequencing &
Hot-Socketing
Because MAX 7000B devices can be used in a mixed-voltage environment,
they have been designed specifically to tolerate any possible power-up
sequence. The VCCIO and VCCINT power planes can be powered in any
order.
Signals can be driven into MAX 7000B devices before and during power-
up (and power-down) without damaging the device. Additionally,
MAX 7000B devices do not drive out during power-up. Once operating
conditions are reached, MAX 7000B devices operate as specified by the
user.
MAX 7000B device I/O pins will not source or sink more than 300 A of
DC current during power-up. All pins can be driven up to 4.1 V during
hot-socketing.
Design Security
All MAX 7000B devices contain a programmable security bit that controls
access to the data programmed into the device. When this bit is
programmed, a design implemented in the device cannot be copied or
retrieved. This feature provides a high level of design security, because
programmed data within EEPROM cells is invisible. The security bit that
controls this function, as well as all other programmed data, is reset only
when the device is reprogrammed.
Generic Testing
MAX 7000B devices are fully functionally tested. Complete testing of each
programmable EEPROM bit and all internal logic elements ensures 100%
programming yield. AC test measurements are taken under conditions
equivalent to those shown in Figure 11. Test patterns can be used and then
erased during early stages of the production flow.
