Speeds down to 7.5 ns and operation up to 166 MHz are offered. All pins offer a low 10 A leakage. The AT22V10B logic functionality is fully compatible with the standard 22V10. The 12 dedicated inputs and ten configurable I/O pins allow implementation of logic requiring up to 22 input signals. The AT22V10B also provides individual output enable product terms for each of the ten I/Os.

Each output is allocated from eight to 16 product terms, which allows highly complex logic functions to be realized. The AT22V10B includes two additional product terms to provide synchronous preset and asynchronous reset. These terms are common to all ten registers. All registers are automatically cleared upon power up. Register preload simplifies testing. A security fuse prevents unauthorized copying of programmed fuse patterns.

This feature will simplify testing since any state can be forced into the registers to control test sequencing. A VIH level on the I/O pin will force the register high; a VIL will force it low, independent of the polarity bit (C0) setting. The preload state is entered by placing an 10.5-V to 12-V signal on pin 8 on DIPs, and pin 10 on SMPs. When the clock pin is pulsed high, the data on the I/O pins is placed into the ten registers.

FORCEI/O'S PRELOAD DATA OUTPUTS DIS. TO VIH ORVIL CLOCKED IN OUTPUT VOLTAGE REMOVED 3.8 V PRELOAD DISABLED Power Up Reset The registers in the AT22V10B are designed to reset during power up. At a point delayed slightly from VCC crossing 3.8 V, all registers will be reset to the low state. The output state will depend on the polarity of the output buffer. This feature is critical for state machine initialization. However, due to the asynchronous nature of reset and the uncertainty of how VCC actually rises in the system, the following conditions are required: 1) The VCC rise must be monotonic, 2) After reset occurs, all input and feedback setup times must be met before driving the clock pin high, and 3) The clock must remain stable during tPR.

Typical values for nominal supply voltage. This parameter is only sampled and is not 100% tested. Erasure Characteristics The entire fuse array of an AT22V10B is erased after exposure to ultraviolet light at a wavelength of 2537 A. Complete erasure is assured after a minimum of 20 minutes exposure using 12,000 2 W/cm intensity lamps spaced one inch away from the chip. Minimum erase time for lamps at other intensity ratings can be 1-114 calculated from the minimum integrated erasure dose of 15 W*sec/cm2. To prevent unintentional erasure, an opaque label is recommended to cover the clear window on any UV erasable PLD which will be subjected to continuous fluorescent indoor lighting or sunlight.
