hi,

sorry, yet another news I hope are useful for Atmel users.

- AT89S83, AT89LS83, AT89S8252 and AT89LS8252 are "Not Recommended for New Designs" status from now. Use AT89S8253 instead.
Here is short info about AT89S8253:

• Compatible with MCS®-51 Products
• 12K Bytes of In-System Programmable (ISP) Flash Program Memory
– SPI Serial Interface for Program Downloading
– Endurance: 10,000 Write/Erase Cycles
• 2K Bytes EEPROM Data Memory
– Endurance: 100,000 Write/Erase Cycles
• 64-byte User Signature Array
• 2.7V to 5.5V Operating Range
• Fully Static Operation: 0 Hz to 24 MHz
• Three-level Program Memory Lock
• 256 x 8-bit Internal RAM
• 32 Programmable I/O Lines
• Three 16-bit Timer/Counters
• Nine Interrupt Sources
• Enhanced UART Serial Port with Framing Error Detection and Automatic Address Recognition
• Enhanced SPI (Double Write/Read Buffered) Serial Interface
• Low-power Idle and Power-down Modes
• Interrupt Recovery from Power-down Mode
• Programmable Watchdog Timer
• Dual Data Pointer
• Power-off Flag
• Flexible ISP Programming (Byte and Page Modes)
– Page Mode: 64 Bytes/Page for Code Memory, 32 Bytes/Page for Data Memory

This document may be useful for reading now: Migrating from AT89S8252/S53 to AT89S8253.

- T89C51CC01 both datasheet and Errata has been updated.
The main difference is that Lots A03874, A03875, A03876 and all lots from A04440 (excluded) are free from next two errors:
- Flash/EEPROM – First Read after Write Disturbed.
- Flash/EEPROM – First Read after Load Disturbed.

- AT89C5130A-M has been anounced. No separate datasheet is available yet. The main difference from AT89C5131A-M is that AT89C5130A-M has 16kb of Flash memory (AT89C5131A-M does 32kb).

Oleg
