MAX1459
the EEPROM (one of the reserved bits), the necessary
commands are:
001C hex: No-OP command, with address 1C hex
in the data field
201C hex: WRITE EEPROM BIT command, with
address 1C hex in the data field
001C hex: No-OP command, with address 1C hex
in the data field
ERASE EEPROM Command (1 hex)
When an ERASE EEPROM command is issued, all of
the memory locations in the EEPROM are reset to a
logic 0. The data field of the 16-bit word is ignored
(Figure 7).
Important: An internal charge pump develops voltages
greater than 20V for EEPROM programming operations.
The EEPROM control logic requires 10ms to erase the
EEPROM. After sending a write or erase command, fail-
ure to wait 10ms before issuing another command may
result in unreliable EEPROM operation. The maximum
number of EEPROM ERASE cycles should not ex-
ceed 100.
WRITE EEPROM BIT Command (2 hex)
The WRITE EEPROM BIT command stores a logic high
at the memory location specified by the lower 7 bits of
the data field (D6–D0). The higher bits of the data field
(D11–D7) are ignored (Figure 8). Note that to write to
the internal EEPROM, WE and CS must be high. In
