Description
The AT28C16-T is the ideal nonvolatile attribute memory: it is a low power, 5-volt-only
byte writable nonvolatile memory (EEPROM). Standby current is typically less than
100 µA. The AT28C16-T is written like a Static RAM, eliminating complex program-
ming algorithms. The fast write cycle times of 1 ms, allow quick card reconfiguration
in-system. Data retention is specified as 10 years minimum, precluding the necessity
for batteries. Three access times have been specified to allow for varying layers of
buffering between the memory and the PCMCIA interface.
The AT28C16-T is accessed like a Static RAM for read and write operations. During a
byte write, the address and data are latched internally. Following the initiation of a
write cycle, the device will go to a busy state and automatically write the latched data
using an internal control timer. The device provides two methods for detecting the end
of a write cycle; the RDY/BUSY output and DATA POLLING of I/O7.
