DATASHEET
s Memories
– Up to 32K of ROM or High Density Flash (HD-
Flash) program memory with read/write pro-
tection
– For HDFlash devices, In-Application Pro-
gramming (IAP) via USB and In-Circuit pro-
gramming (ICP)
– Up to 5 Kbytes of RAM with up to 256 bytes
stack
s Clock, Reset and Supply Management
– PLL for generating 48 MHz USB clock using a
12 MHz crystal
– Low Voltage Reset (except on E suffix devic-
es)
– Dual supply management: analog voltage de-
tector on the USB power line to enable smart
power switching from USB power to battery
(on E suffix devices).
– Programmable Internal Voltage Regulator for
Memory cards (2.8V to 3.5V) supplying:
Flash Card I/O lines (voltage shifting)
Up to 50 mA for Flash card supply
– Clock-out capability
s 47 programmable I/O lines
– 15 high sink I/Os (8mA @0.6V / 20mA@1.3V)
– 5 true open drain outputs
– 24 lines programmable as interrupt inputs
s USB (Universal Serial Bus) Interface
– with DMA for full speed bulk applications com-
pliant with USB 12 Mbs specification (version
2.0 compliant)
– On-Chip 3.3V USB voltage regulator and
transceivers with software power-down
– 5 USB endpoints:
1 control endpoint
2 IN endpoints supporting interrupt and bulk
2 OUT endpoints supporting interrupt and
bulk
– Hardware conversion between USB bulk
packets and 512-byte blocks
