FlashFlex MCU

SST89E54RD2A/RDA / SST89E58RD2A/RDA

A Microchip Technology Company

Not Recommended for New Designs

The SST89E54RD2A/RDA and SST89E58RD2A/RDA are members of the Flash-

Flex family of 8-bit microcontroller products designed and manufactured with SST

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 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

• Programmable Counter Array (PCA)

• Four 8-bit I/O Ports (32 I/O Pins) and

One 4-bit Port

– Fully Software Compatible

– Development Toolset Compatible

– Pin-For-Pin Package Compatible

• Second DPTR register

• Low EMI Mode (Inhibit ALE)

• SPI Serial Interface

• SST89E5xRD2A Operation

– 0 to 40 MHz at 5V

• 1 KByte Internal RAM

• Standard 12 Clocks per cycle, the device has an

option to double the speed to 6 clocks per cycle.

• Dual Block SuperFlash EEPROM

– 16/32 KByte primary block +

8 KByte secondary block

• TTL- and CMOS-Compatible Logic Levels

• Brown-out Detection

(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

• Low Power Modes

– Power-down Mode with External Interrupt Wake-up

• Support External Address Range up to 64 KByte

of Program and Data Memory

– Idle Mode

• Temperature Ranges:

• Three High-Current Drive Ports (16 mA each)

• Three 16-bit Timers/Counters

– Commercial (0°C to +70°C)

• Packages Available

– 44-lead PLCC

• Full-Duplex, Enhanced UART

– 40-pin PDIP (Port 4 feature not available)

– 44-lead TQFP

– Framing Error Detection

– Automatic Address Recognition

• All non-Pb (lead-free) devices are RoHS compliant

• Ten Interrupt Sources at 4 Priority Levels

– Four External Interrupt Inputs

• Programmable Watchdog Timer (WDT)
