Microchip (AT89C2051-24PU) 8 Bit MCU, 24 MHz, 2 KB, 20 Pins, DIP

8 Bit MCU, 8051 Family AT89C2051 Series Microcontrollers, 24 MHz, 2 KB, 20 Pins, DIP Product Overview The AT89C2051-24PU is a low voltage, high performance CMOS 8bit microcontroller in 20 pin DIP package. The device is manufactured using high density non volatile memory technology and is compatible with industry standard MCS-51 instruction set. It provides highly flexible and cost effective solution to many applications by combining versatile 8bit CPU with flash on monolithic chip. The AT89C2051-24PU has on-chip analogue comparator, on-chip oscillator, clock circuitry, low power idle and power down modes. This microcontroller is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The power down mode saves RAM contents but freezes oscillator disabling all other chip functions until the next hardware reset. Fully static operation from 0Hz to 24MHz 2KB of reprogrammable flash memory Two level program memory lock 128 x 8bit internal RAM 15 programmable I/O lines Two 16bit timer/counters Six interrupt sources Operating voltage range from 4V to 6V Programmable serial UART channel Operating temperature range from -40°C to 85°C Product Information Product Range: 8051 Family AT89C2051 Series Microcontrollers CPU Speed: 24MHz Program Memory Size: 2KB Operating Frequency Max: 24MHz RAM Memory Size: 128Byte No. of Pins: 20Pins MCU Case Style: DIP IC Case / Package: DIP No. of I/O's: 15I/O's Embedded Interface Type: UART Interfaces: UART Supply Voltage Min: 2.7V Supply Voltage Max: 6V MCU Family: 8051 MCU Series: AT89C2051 Operating Temperature Min: -40°C Operating Temperature Max: 85°C IC Mounting: Through Hole
