Differences Between the D-Series and
C-Series Cards
The differences between the D-Series Card and the
earlier C-Series Cards are as follows:
s The D-Series Cards are based on AMD’s latest 16
MBit 5.0 Volt-only device, the Am29F016C. The ear-
lier C-Series Cards were based on the 4 MBit 5.0
Volt-only device, the Am29F040.
s The D-Series Cards program faster than the C-
Series Cards. This is due to faster byte write times
and an optimized address unlock sequence for
write operations.
s The D-Series Cards are offered in higher densi-
ties. The D-Series Cards are available in densities
of 4 MBytes, 8 MBytes, 20 MBytes, and 32
MBytes. The earlier C-Series Cards were avail-
able in densities of 1 MByte, 2 MBytes, 4 MBytes
and 10 MBytes.
The additional features that are supported in the new
D-Series Cards include
s The D-Series Cards support the RESET feature.
This allows you to asynchronously RESET the Card
into the read state.
s The D-Series Cards also provide the RY/BY func-
tionality. This feature provides a quick way of deter-
mining if the Card is busy doing a write or erase
operation, or if it is in a position to undertake the
next operation.
s Availability of an additional Toggle bit (D2) to deter-
mine if the Card is in the Embedded Erase or Erase
Suspend mode.
s Programming operations can be executed in 8 µs
pulses, down from the 16 µs on the C-Series
Cards (typical).
s Time out from the rising edge of the WE pulse for
sector erase command reduced from 100 µs to
50 µs.
s The D-Series Cards offers a low power standby
mode with fast recovery time to read. The typical
standby current (I_CCS) is <1 µA with recovery at
standard read access time.
