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.


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
