89V52RD2 datasheet

 

Description :

The SST89E5xxRD2 and SST89V5xxRD2 are members of the FlashFlex51 family of 8-bit microcontroller products designed and manufactured with SST’s patented and proprietary SuperFlash CMOS semiconductor process technology. The split-gate cell design and thick-oxide tunneling injector offer significant cost and reliability benefits for SST’s customers. The devices use the 8051 instruction set and are pin-for-pin compatible with standard 8051 microcontroller devices.

Features

1.8-bit 8051-Compatible Microcontroller (MCU)
2. Programmable Watchdog Timer (WDT)
3. Programmable Counter Array (PCA)
4. Four 8-bit I/O Ports (32 I/O Pins) and One 4-bit Port
5. Second DPTR register
6. Low EMI Mode (Inhibit ALE)
7. SPI Serial Interface
8. 1 KByte Internal RAM
9. Dual Block SuperFlash EEPROM

NM24C32UM8 Datasheet PDF – 32K-Bit Serial EEPROM

Part Number : NM24C32UM8

Function : 32K-Bit Serial EEPROM with Write Protect 2-Wire Bus Interface

Package : DIP, SO 8 Pin Type

Manufacturers : Fairchild Semiconductor

Pinouts :

NM24C32UM8 datasheet

Description :

The NM24C32 devices are 32,768 bits of CMOS nonvolatile electrically erasable memory. These devices offer the designer different low voltage and low power options, and they conform to all specifications in the Extended IIC 2-wire protocol. Furthermore, they are designed to minimize device pin count and simplify PC board layout requirements.

Functions :

1. I2C Compatible interface
2. 32,768 bits organized as 4,096 x 8
3. Extened 2.7V – 5.5V operating voltage
4. 100 KHZ or 400 KHZ operation

Features :

1. The I2C interface allows the smallest I/O pincount of any EEPROM interface
2. 32 byte page write mode to minimize total write time per byte
3. Typical 200µA active current ( Icca )
