PRODUCT DESCRIPTION The SST89E5xRD2/RD and SST89V5xRD2/RD 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: • 8-bit 8051-Compatible Microcontroller (MCU) with Embedded SuperFlash Memory – Fully Software Compatible – Development Toolset Compatible – Pin-For-Pin Package Compatible • SST89E5xRD2 Operation – 0 to 40 MHz at 5V • SST89V5xRD2 Operation – 0 to 33 MHz at 3V • 1 KByte Internal RAM • Dual Block SuperFlash EEPROM – 8/16/32 KByte primary block + 8 KByte secondary block (128-Byte sector size for both blocks) – Individual Block Security Lock with SoftLock – Concurrent Operation during In-Application Programming (IAP) – Memory Overlay for Interrupt Support during IAP • Support External Address Range up to 64 KByte of Program and Data Memory • Three High-Current Drive Ports (16 mA each) • Three 16-bit Timers/Counters • Full-Duplex, Enhanced UART – Framing Error Detection – Automatic Address Recognition • Ten Interrupt Sources at 4 Priority Levels – Four External Interrupt Inputs • Programmable Watchdog Timer (WDT) • Programmable Counter Array (PCA) • Four 8-bit I/O Ports (32 I/O Pins) and One 4-bit Port • Second DPTR register • Low EMI Mode (Inhibit ALE) • SPI Serial Interface • Standard 12 Clocks per cycle, the device has an option to double the speed to 6 clocks per cycle. • TTL- and CMOS-Compatible Logic Levels • Brown-out Detection • Low Power Modes – Power-down Mode with External Interrupt Wake-up – Idle Mode • Temperature Ranges: – Commercial (0°C to +70°C) – Industrial (-40°C to +85°C) • Packages Available – 40-contact WQFN (Port 4 feature not available) – 44-lead PLCC – 40-pin PDIP (Port 4 feature not available) – 44-lead TQFP • All non-Pb (lead-free) devices are RoHS compliant
