PALCE22V10 and PALCE22V10Z Families
5
Note that preset and reset control the ip-op, not the output pin. The output level is determined
by the output polarity selected.
Power-Up Reset
All ip-ops power up to a logic LOW for predictable system initialization. Outputs of the
PALCE22V10 will depend on the programmed output polarity. The VCC rise must be monotonic,
and the reset delay time is 1000ns maximum.
Register Preload
The register on the PALCE22V10 can be preloaded from the output pins to facilitate functional
testing of complex state machine designs. This feature allows direct loading of arbitrary states,
making it unnecessary to cycle through long test vector sequences to reach a desired state. In
addition, transitions from illegal states can be veried by loading illegal states and observing
proper recovery.
Security Bit
After programming and verication, a PALCE22V10 design can be secured by programming the
security EE bit. Once programmed, this bit defeats readback of the internal programmed pattern
by a device programmer, securing proprietary designs from competitors. When the security bit is
programmed, the array will read as if every bit is erased, and preload will be disabled.
The bit can only be erased in conjunction with erasure of the entire pattern.
Programming and Erasing
The PALCE22V10 can be programmed on standard logic programmers. It also may be erased to
reset a previously congured device back to its unprogrammed state. Erasure is automatically
performed by the programming hardware. No special erase operation is required.
Quality and Testability
The PALCE22V10 offers a very high level of built-in quality. The erasability of the device provides
a direct means of verifying performance of all AC and DC parameters. In addition, this veries
complete programmability and functionality of the device to provide the highest programming
yields and post-programming functional yields in the industry.
Technology
The high-speed PALCE22V10 is fabricated with Vantis’ advanced electrically erasable (EE) CMOS
process. The array connections are formed with proven EE cells. Inputs and outputs are designed
to be compatible with TTL devices. This technology provides strong input clamp diodes, output
slew-rate control, and a grounded substrate for clean switching.
PCI Compliance
The PALCE22V10H devices in the -5/-7/-10 speed grades are fully compliant with the PCI Local
Bus Specication published by the PCI Special Interest Group. The PALCE22V10H’s predictable
timing ensures compliance with the PCI AC specications independent of the design.
Zero-Standby Power Mode
The PALCE22V10Z features a zero-standby power mode. When none of the inputs switch for an
extended period (typically 50 ns), the PALCE22V10Z will go into standby mode, shutting down
