HD74LS393FP(SMD)

The HD74LS393FP(SMD) is designed as one kind of CMOS microcomputer unit (MCU) that comprising a CPU core plus a full range of supporting functions-an entire system integrated onto a single chip. And this CPU features a highly orthogonal instruction set that permits addressing modes and data sizes to be specified independently in each instruction. An on-chip data transfer controller (DTC) can transfer data in either direction between memory and I/O independently of the CPU.

Features of the HD74LS393FP(SMD) are:(1)Eight 16-bit general registers;(2)Five 8-bit and two 16-bit control registers;(3)Addressing modes and data size can be specified independently for each instruction;(4)Instruction set optimized for C language;(5)2-kbyte high-speed RAM on-chip;(6)32-kbyte programmable or masked ROM on-chip;(7)One 8-bit up-counter (which can count external events);(8)Generates pulses with any duty ratio from 0 to 100%;(9)Asynchronous or synchronous mode (selectable);(10)Full duplex: can send and receive simultaneously.

The absolute maximum ratings of the HD74LS393FP(SMD) can be summarized as:(1)Supply voltage:0.3 to +7.0 V;(2)Programming voltage (R-mask):0.3 to +13.5 V;(3)Programming voltage (S-mask):0.3 to +13.0 V;(4)Analog supply voltage:0.3 to +7.0 V;(5)Analog input voltage:0.3 to AVCC + 0.3 V;(6)Storage temperature:65 to +150 °C.
