AT91SAM7S256 Errata - Revision C Parts
AT91SAM7S Series Preliminary
Embedded Flash Controller (EFC)
Parallel Input/Output Controller (PIO)
EFC: Embedded Flash Access Time 1
PIO: Electrical Characteristics on NRST and PA0-PA16 and PA21-31
PIO: Drive Low NRST, PA0-PA16 and PA21-PA31
Refer to
Note: AT91SAM7S256 Revision C chip ID is 0x270B 0942.
The embedded Flash maximum access time is 20 MHz (instead of 30 MHz) at zero Wait State
(FWS = 0).
The maximum operating frequency with one Wait State (FWS = 1) is 48.1 MHz (instead of
55 MHz). Above 48.1 MHz and up to 55 MHz, two Wait States (FWS = 2) are required.
Set the number of Wait States (FWS) according to the frequency requirements described in this
errata.
When NRST or PA0-PA16 or PA21-PA31 are set as digital inputs with pull-up enabled, the volt-
age of the I/O stabilizes at VPull-up.
Vpull-up
This condition causes a leakage through VDDIO. This leakage is 45 µA per pad in worst case at
3.3 V, and 25 µA at 1.8V.
I Leakage
It is recommended to use an external pull-up if needed.
When NRST or PA0-PA16 and or PA21-PA31 are set as digital inputs with pull-up enabled, driv-
ing the I/O with an output impedance higher than 500 ohms may not drive the I/O to a logical
zero.
Output impedance must be lower than 500 ohms.
