Low-cost Cortex-M0 USB solutions with

Smart Card interface

Features

`

` ARM`Cortex-M0`processor,`running`at`frequencies`of`up`to`

50`MHz

`

` Memory:

-`Up`to`32`kB`on-chip`flash`program`memory

-``Total`of`6`kB`SRAM`data`memory`(4`kB`main`SRAM`and`

2`kB`USB`SRAM)

-``16`kB`boot`ROM

-``In-System`Programming`(ISP)`and`In-Application`

Programming`(IAP)`via`on-chip`bootloader`software

`

` Debug`options:

-``Standard`JTAG`test/debug`interface.`Serial`Wire`Debug

-``Boundary`scan`for`simplified`board`testing

`

` Up`to`40`General-Purpose`I/O`(GPIO)`pins`with`configurable`

pull-up/pull-down`resistors,`repeater`mode,`and`open-drain`

mode

-``Two`GPIO`grouped`interrupt`modules`enable`an`interrupt`

based`on`a`programmable`pattern`of`input`states`of`a`

group`of`GPIO`pins

Delivering`robust`USB`performance`at`a`low`price`point,`these`low-cost`devices`are`compelling`

replacements`for`8/16-bit`USB`microcontrollers.`The`highly`flexible`USB`architecture`is,`quite`

simply,`a`better`approach`to`USB.`NXP`offers`the`widest`range`of`ARM-based`USB`solutions,`as`

well`as`easy-to-use`software`and`integrated`development`platforms`that`make`NXP`a`one-stop`

shop`for`USB.
