AT91 Flash Uploader Software
Flash Uploader Operations
Programming) is exited by powering down the device or by pulsing the NRSTF pin low for a
defined duration
The following hardware features protect against inadvertent programming of the Flash
memory:
See the AT49BV1604A/1614A(T) 2-Mbyte (1M x 16/2M x 8) 3-volt Only Flash Memory
Datasheet for further details on Flash operation and electrical characteristics.
Note:
All Flash-based AT91 devices are delivered with a pre-programmed software called the AT91
Flash Uploader, which resides in the first sector of the embedded Flash. The Flash Uploader
allows programming to the embedded flash through a serial port. Either of the on-chip
USARTs can be used by the Flash Uploader.
Figure 7-1.
The Flash Uploader requires the encapsulated Flash to be used as the AT91FR40162 boot
memory and a valid clock to be applied to MCKI. After reset, the Flash Uploader immediately
recopies itself into the internal SRAM and jumps to it. The following operation requires this
• VDDIO Sense – if VDDIO is below a certain level
• VDDIO Power-on Delay – once VDDIO has reached the VDDIO sense level, the device will
• Program Inhibit – holding any one of OE low, CE high or WE high inhibits program cycles.
• Noise Filter – pulses of less than a certain duration
automatically time out a certain duration
initiate a program cycle.
