The SNx4HC595 devices contain an 8-bit, serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The storage register has parallel 3-state outputs. Separate clocks are provided for both the shift and storage register. The shift register has a direct overriding clear (SRCLR) input, serial (SER) input, and serial outputs for cascading. When the output-enable (OE) input is high, the outputs are in the high-impedance state.
Part Number：M48T86MH1
Manufacturer：STMicroelectronics
Category ：Integrated Circuits Clock/Timing Real Time Clocks
Description ：Real Time Clock (RTC) IC Clock/Calendar 114B Parallel 28-SOP (0.350", 8.89mm Width) with SNAPHAT Sockets
Features：Alarm, Leap Year, NVSRAM, Square Wave Output
The M48T86 is an industry standard real-time clock (RTC). The M48T86 is composed of a lithium energy source, quartz crystal, write protection circuitry, and a 128-byte RAM array.
This provides the user with a complete subsystem packaged in either a 24-pin DIP CAPHAT™ or 28-pin SNAPHAT® SOIC. Functions available to the user include a nonvolatile time-of-day clock, alarm interrupts, a one-hundred-year clock with programmable interrupts, square wave output, and 128 bytes of non-volatile static RAM.
The 24-pin, 600 mil DIP CAPHAT houses the M48T86 silicon with a quartz crystal and a long-life lithium button cell in a single package.
The 28-pin, 330 mil SOIC provides sockets with gold plated contacts at both ends for direct connection to a separate SNAPHAT® housing containing the battery and crystal. The unique design allows the SNAPHAT battery package to be mounted on top of the SOIC package after the completion of the surface mount process.
Insertion of the SNAPHAT housing after reflow prevents potential battery and crystal damage due to the high temperatures required for device surface-mounting. The SNAPHAT housing is keyed to prevent reverse insertion.
The SOIC and battery packages are shipped separately in plastic anti-static tubes or in tape & reel form.

Part Number：ATTINY44V-10SSUR
Manufacturer：Microchip Technology
Category ：Integrated Circuits Embedded Microcontrollers
Description ：AVR AVR® ATtiny Microcontroller IC 8-Bit 10MHz 4KB (2K x 16) FLASH 14-SOIC
ATtiny24/44/84 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny24/44/84 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
The ATtiny24/44/84 provides the following features: 2/4/8K byte of In-System Programmable Flash, 128/256/512 bytes EEPROM, 128/256/512 bytes SRAM, 12 general purpose I/O lines, 32 general purpose working registers, an 8-bit Timer/Counter with two PWM channels, a 16-bit timer/counter with two PWM channels, Internal and External Interrupts, a 8-channel 10-bit ADC, programmable gain stage (1x, 20x) for 12 differential ADC channel pairs, a programmable .
Watchdog Timer with internal oscillator, internal calibrated oscillator, and four software selectable power saving modes. Idle mode stops the CPU while allowing the SRAM, Timer/Counter, ADC, Analog Comparator, and Interrupt system to continue functioning. ADC Noise Reduction mode minimizes switching noise during ADC conversions by stopping the CPU and all I/O modules except the ADC. In Power-down mode registers keep their contents and all chip functions are disbaled until the next interrupt or hardware reset. In Standby mode, the crystal/resonator oscillator is running while the rest of the device is sleeping, allowing very fast start-up combined with low power consumption.
The device is manufactured using Atmel’s high density non-volatile memory technology. The onchip ISP Flash allows the Program memory to be re-programmed in-system through an SPI
serial interface, by a conventional non-volatile memory programmer or by an on-chip boot code running on the AVR core.
The ATtiny24/44/84 AVR is supported with a full suite of program and system development tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators and Evaluation kits.
