VC6289/VC6417
The VC6289 and VC6417 are reversible-motor drivers, with an output current of 600mA for the former and 1A for thelatter. Two logic inputs allow four output modes: forward, reverse, stop (idling), and brake. A built-in power saving circuit
suppresses current consumption when the motor is in stop mode.
VC8563 Real-time clock/calendar
The VC 8563 is a CMOS' Real-Time Clock (RTC) and calendar optimized for low powerconsumption. A programmable clock output, interrupt output, and voltage-low detector arealso provided, All addresses and data are transferred serially via a two-line bidirectiona2C-bus. Maximum bus speed is 400 kbit/s. The register address is incrementedautomatically after each written or read data byte.
FS9140S_192_

FS9140S is a 192-bit CMOS driver for thermal printer head. It includes 192 built-in shift registers to transfer the data, and 192 latches to hold the input data.
