| CA3309 CA3309 PDF DISTINCTIVE CHARACTERISTICS n Ideal for Fiber-In-The-Loop (FITL) applications n Low standby power n C21 V to C58 V battery operation n On-chip battery switching and feed selection n On-hook transmission n Two-wire impedance set by single external CA3309 Datasheet The CA3309 is capable of an 8-byte page write. A page write is initiated the same way as a byte write, but the master does not send a stop condition after the first data byte. Instead, after the slave acknowledges the data byte has been received, the master can send up to seven more data bytes using the same nine- clock sequence. After a write to the last byte in the page, the address returns to the beginning of the same page. The master must then terminate the write cycle with a stop condition or the data clocked into the CA3309 Suppliers The CA3309 is capable of an 8-byte page write.

The ability to reuse existing architecture and firmware investments shortens the development time, eliminates risk and reduces cost. The result is fast and efficient development of the most cost-effective USB peripheral solution. technology. Integrated into the single chip are on chip watchdog (WDT), RAM, ROM, programmable real-time clock/counter, internal interrupt, power-down mode, LCD driver, and tri-state I/O. The CA3309 provides a single chip solution for designing DATA-BANK of message display. Soldering Temperature (10 sec, 1/16 from case)TL260C 1. Isolation surge voltage is an internal device dielectric breakdown rating. 1. For this test, Pins 1 and 2 are common, and Pins 4 and 5 are common. 2. Refer to Quality and Reliability Section in Opto Data Book for information on test conditions. |
