• Manufacturer Part Number: A29L400A
• Description: 512K X 8 Bit / 256K X 16 Bit CMOS 3.0 Volt-only, Boot Sector Flash Memory
• Manufacturer: AMICC [AMIC Technology]

CMOS standby current (I
within VSS ± 0.3V, the standby current will be greater.
The RESET pin may be tied to the system reset circuitry. A
system reset would thus also reset the Flash memory,
enabling the system to read the boot-up firmware from the
Flash memory.
If RESET is asserted during a program or erase operation,
the RY/
operation is complete, which requires a time t
Embedded Algorithms). The system can thus monitor
