N76E003AT20 IC -Pack of 5Pcs

220.00Rs. 200.00Rs.

The N76E003 is an embedded flash type, 8-bit high performance 1T 8051-based microcontroller. The
instruction set is fully compatible with the standard 80C51 and performance enhanced.
The N76E003 contains a up to 18K Bytes of main Flash called APROM, in which the contents of User
Code resides. The N76E003 Flash supports In-Application-Programming (IAP) function, which
enables on-chip firmware updates. IAP also makes it possible to configure any block of User Code
array to be used as non-volatile data storage, which is written by IAP and read by IAP or MOVC
instruction. There is an additional Flash called LDROM, in which the Boot Code normally resides for
carrying out In-System-Programming (ISP). The LDROM size is configurable with a maximum of 4K
Bytes. To facilitate programming and verification, the Flash allows to be programmed and read
electronically by parallel Writer or In-Circuit-Programming (ICP). Once the code is confirmed, user can
lock the code for security.
