SUPPORTED SPI DEVICES

The supported devices are those that conform to the

JEDEC−compliant programming interface

. Please contact

ON Semiconductor for specific design criteria and

requirements. The maximum supported device size is 2 Gb.

HOST COMMAND INTERFACE

The AS0142AT has a mechanism to write higher level

commands thru the Host Command Interface (HCI). Once

a command has been written through the HCI

, it will be

executed by on chip firmware and the results are reported

back. EEPROM or Flash memory is also available to store

commands for later execution.

Full details of the Host Command Interface can be found

in the AS0142AT Host Command Interface (HCI)

Specification document.

SPECIFICATIONS

Caution: Stresses greater than those listed in Table 23 may

cause permanent damage to the device

. This is a stress rating

only, and functional operation of the device at these or any

other conditions above those indicated in the operational

sections of this specification is not implied. Exposure to

absolute maximum rating conditions for extended periods

may affect reliability.
