General Architecture Atmel Secure Microcontroller
Using embedded Flash program memory, Atmel's secure microcontrollers offer some significant benefits over ROM:
Atmel. offers widest choice secure microcontrollers only secure microcontroller supplier that offer customers Flash today
Faster time-to-market:
Flash allows just-in-time software loading Flash maximizes parallelism software development silicon manufacture Flash reduces zero lead time software updates Flash enables device used multiple applications Flash enables code optimized each application
Excellent security:
Flash intrinsically secure thanks invisibility impossible extract code visual inspection, Ebeam inspection erases memory matrix Evaluated independent laboratories Flash eliminates mask charges
Increased flexibility:
Cost reduction:
Flash memory type nonvolatile memory (NVM). retains contents when powered down. Information read from address Flash time, only erased re-written pages (e.g. bytes). Atmel's Flash memory guaranteed minimum 10,000 erase/write cycles years data retention.

Code Development
Atmel pioneer market leader nonvolatile memory technology. Atmel holds number fundamental Flash patents sold hundreds millions Flash memory Flash-based microcontroller ICs. Their reliability been proved thousands end-user products intensive use. Today Atmel able offer embedded Flash program memory option entire range secure microcontroller ICs. Flash Operating System Application Code microcontrollers, embedded Flash memory used store operating system well code some applications. EEPROM used store other applications data, static used workspace. these on-chip memory blocks accessed secure access control block. This prevents unauthorized memory access, creates firewalls between different applications.
Emulation Complete Application Time Validation Volume Sample Devices
Flash Eliminates Software Update Lead Times Flash completely eliminates semiconductor manufacturing lead time program release. Even code loaded Atmel, this operation performed during final test phase. soon version program ready, loaded into next production batch, switchover from software release done seamlessly! addition, there mask charges version.
Flash reduced time-to-market with additional cost First Devices Customer Production ramp-up start immediately from stock general-purpose devices

Flash reduces time-to-market software development upgrades
Flash Loaded during Device Test Personalization Flash-based microcontroller delivered either with program code loaded factory with boot program. This loading operation integral part test cycle does involve additional delays costs. Test last step production cycle. This means that software development take place parallel with silicon manufacture, with last-minute revisions incorporated. Generic products loaded with boot code ready used different applications. These products also ideal evaluation applications. boot program allows system integrator using secure protocol load application code into Flash product assembly site. After loading, Flash made read-only improve security. This gives greatly improved flexibility development time. With Flash memory, possible validate functionality system using sample device, without waiting masked ROM. then, production ramp start immediately programming stocked devices. Atmel Manages Inventory Atmel schedule re-schedule) production batches same device with different Flash content. this way, inventory precisely balanced against demand. Flash Multi-application Devices With Flash memory, single product handle several applications. This helps reduce inventory shorten product introduction phase. From stock general-purpose devices, system integrator chose load program particular application required. This also helps reduce inventory. Flash Offers Much Better Security difficult, performing reverse engineering, determine contents Flash memory. on-chip security systems detect most types attack erase Flash contants before probed. With ROM, content given visible physical patterns, therefore much easier crack without recourse probing. Atmel's security measures have been validated independant laboratories (ITSEC, Common Criteria Security Profile). Flash Allows Optimized Code Most operating systems applications contain additional code minimize impact software bugs, more generic avoid several masks production. With Flash, those constraints disappear, since code entirely tested with final device different codes possible standard product. Each code therefore optimized application. This reduces memory capacity required, hence cost. Flash Ahead Flash memory clearly ahead secure microcontrollers. offers winning combination flexibility, security faster timeto-market, additional cost.
