Device ID
VPP Features
The AT91FR40162SB is a member of the Atmel AT91 16/32-bit Microcontroller family, which is
based on the ARM7TDMI processor core. The processor has a high-performance 32-bit RISC
architecture with a high-density 16-bit instruction set and very low power consumption.
The AT91FR40162SB ARM microcontroller features 2 Mbits of on-chip SRAM and 2 Mbytes of
Flash memory in a single compact 121-ball BGA package. Its high level of integration and very
small footprint make the device ideal for space-constrained applications. The high-speed on-
chip SRAM enables a performance of up to 74 MIPs in typical conditions with significant power
reduction and EMC improvement over an external SRAM implementation.
The Flash memory may be programmed via the JTAG/ICE interface or the factory-programmed
Flash Memory Uploader (FMU) using a single device supply, making the AT91FR40162SB suit-
able for in-system programmable applications.
The AT91FR40162SB is pin-to-pin compatible to the AT91FR40162S, so the AT91FR40162SB
can be soldered in place of the AT91FR40162S without any other hardware changes.
The AT91FR40162SB does not feature a VPP pin, thus ball D5 of the 121-ball BGA package of
the AT91FR40162SB is NC (Not connected). This ball can either be connected to a supply up to
13V (as could be the VPP ball of the AT91FR40162S), grounded or left unconnected.
Except for the Flash memory, the processor, the architecture and the peripherals of both the
AT91FR40162S and the AT91FR40162SB are identical, any program written for an

AT91FR40162SB, with the exception of aspects related to the Flash memory.
Som e features of the embedded Flash memories in the AT91FR40162S and the
AT91FR40162SB are not fully identical.
The Device Code of the Flash Memory of the AT91FR40162SB is 01C0H instead of 00C0H for
the AT91FR40162S. Users who this Device Code must modify the software.
As the AT91FR40162SB does not feature a VPP pin, neither the write protection feature nor the
double-word fast write feature are available on this device.
If the hardware write protection feature is used on the AT91FR40162S, it should be replaced by
a software-controlled write protection method with the Sector Lockdown command, or removed
from the application.
If the Double Byte/Word Program command was used on the AT91FR40162S, the user needs to
change the flash programming sequence and to use only the standard Byte/Word Program
command.
