8 Bit MCU, 8051 Family AT89S8253 Series Microcontrollers, 24 MHz, 12 KB, 40Pins, DIPProduct OverviewThe AT89S8253-24PU is a 8-bit low-power high-performance CMOS Microcontrollerwith 12kB of In-System Programmable (ISP) flash program memory and 2kB of EEPROMdata memory. The device is manufactured using high-density non-volatile memorytechnology and is compatible with the industry-standard MCS-51 instruction setand pinout. The on-chip downloadable flash allows the program memory to bereprogrammed in-system through an SPI serial interface or by a conventionalnon-volatile memory programmer. By combining a versatile 8-bit CPU withdownloadable flash on a monolithic chip, the AT89S8253 is a powerfulmicrocontroller which provides a highly-flexible and cost-effective solution tomany embedded control applications.Compatible with MCS®-51 products12kB of In-System Programmable (ISP) flash program memory2kB EEPROM data memory64-byte user signature arrayThree-level program memory lock256 x 8-bit Internal RAM32 Programmable I/O linesThree 16-bit timers/countersNine interrupt sourcesEnhanced UART serial port with framing error detection and automatic addressrecognitionEnhanced SPI (double write/read buffered) serial interfaceLow-power idle and power-down modesInterrupt recovery from power-down modeProgrammable watchdog timerDual data pointerPower-off flagFlexible ISP programming (byte and page mode)Four-level enhanced interrupt controllerProgrammable and fuse-able x2 clock optionInternal power-on resetProduct InformationProduct Range: 8051 Family AT89S8253 Series MicrocontrollersCPU Speed: 24MHzProgram Memory Size: 12KBOperating Frequency Max: 24MHzRAM Memory Size: 256ByteNo. of Pins: 40PinsMCU Case Style: DIPIC Case / Package: DIPNo. of I/O's: 32I/O'sEmbedded Interface Type: SPI, UARTInterfaces: SPI, UARTSupply Voltage Min: 2.7VSupply Voltage Max: 5.5VMCU Family: 8051MCU Series: AT89S8253Operating Temperature Min: -40°COperating Temperature Max: 85°CIC Mounting: Through HoleQualification: -
