MC68HC05BD3

The MC68HC05BD3 is a kind of HCMOS microcontroller which is a member of the M68HC05 Family of low-cost single-chip microcontrollers. This 8-bit microcontroller unit (MCU) contains an on-chip oscillator, CPU, RAM, ROM, parallel I/O capability with pins programmable as input or output, M-Bus serial interface system (I2C), Pulse Width Modulator, Multi-Function Timer, and Sync Signal Processor.

The following is about the features of MC68HC05BD3: (1)fully static chip design featuring the industry standard 8-bit M68HC05 core; (2)power saving Wait mode; (3)128 bytes of on-chip RAM; (4)3.75K-bytes of user ROM; (5)24 bidirectional I/O lines: 14 dedicated and 10 multiplexed I/O lines. 4 of the 14 dedicated I/O lines and 6 of the MUXed I/O lines have +10V open-drain O/Ps; (6)16 channels PWM outputs: 8 dedicated, +10V open-drain PWM channels and 8 multiplexed with I/O lines of which 6 of them have +10V open-drain outputs; (7)m-bus serial interface (I2C-bus); (8)multi-function timer (MFT) with periodic interrupt; (9)COP watchdog reset; (10)horizontal and Vertical Sync Signal Processor; (11)self-check mode; (12)available in 40-pin DIP and 42-pin SDIP packages.

The last one is about the maximum ratings of MC68HC05BD3: (1)supply voltage, VDD: -0.3 to +7.0 V; (2)input voltage, Vin: VSS-0.3 to VDD+0.3 V; (3)IRQ, Vin: VSS-0.3 to 2*VDD+0.3 V; (4)current drain per pin excluding VDD and VSS, ID: 25 mA; (5)operating temperature, TA: 0 to 70; (6)storage temperature range, Tstg: -65 to +150.
