The hardware RESET# pin terminates any operation in progress and resets the internal state
machine to reading array data. The RESET# pin may be tied to the system reset circuitry. A
system reset would thus also reset the device, enabling the system microprocessor to read the
boot-up firmware from the Flash memory.
The device offers two power-saving features. When addresses have been stable for a specified
amount of time, the device enters the automatic sleep mode. The system can also place the
device into the standby mode. Power consumption is greatly reduced in both these modes.
ESI’s Flash technology combines years of Flash memory manufacturing experience to produce the
highest levels of quality, reliability and cost effectiveness. The device electrically erases all bits
within a sector simultaneously via Fowler-Nordheim tunneling. The data is programmed using hot
electron injection.

7. Device Bus Operations
This section describes the requirements and use of the device bus operations, which are initiated
through the internal command register. The command register itself does not occupy any
addressable memory location. The register is composed of latches that store the commands, along
with the address and data information needed to execute the command. The contents of the
register serve as inputs to the internal state machine. The state machine outputs dictate the
function of the device. Table 7.1 lists the device bus operations, the inputs and control levels they
require, and the resulting output. The following subsections describe each of these operations in
further detail.

Notes
1. Addresses are A19:A0 in word mode (BYTE# = VIH), A19:A-1 in byte mode (BYTE# = VIL).
2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See Sector
Protection/ Unprotection on page 18.
