| CA3310M CA3310M PDF The Write Protect Enable (WPEN) bit is a nonvolatile bit that is available as an enable bit for the WP pin. The Write Protect (WP) pin and the Write Protect Enable (WPEN) bit in the status register control the programmable hardware write protect feature. Hardware write protection is enabled when the WP pin is low and the WPEN bit is high. Hardware write protection is disabled when either the WP pin is high or the WPEN bit is low. When the chip is hardware write protected, only writes to nonvolatile bits in the status register are disabled. See Table 2-2 for matrix of functionality on the WPEN bit and Figure 2-1 for a flowchart of Table 2-2. CA3310M Datasheet NOTES 1. Absolute maximum rating specifies the values beyond which the device may be damaged permanently. Exposure to ABSOLUTE MAXIMUM RATING conditions for extended periods may affect reliability. Each condition value is applied with the other values kept within the following operating conditions and function operation under any of these conditions is not implied. 2. All voltages are measured with respect to VSS unless otherwise specified. 3. 100pF capacitor is discharged through a 1.5kΩ resistor (Human body model) CA3310M Suppliers The circuit of the TSOP18..UH1 is designed in that way that unexpected output pulses due to noise or disturbance signals are avoided. A bandpassfilter, an integrator stage and an automatic gain control are used to suppress such disturbances. The distinguishing mark between data signal ( not suppressed) and disturbance signal (supressed) are carrier frequency, burst length and Signal Gap Time (see diagram below). The HT812L0 provides a maximum of 8 keys, 2 status indicator driving pins and a current type D/A output. Of the 8 keys, only KEY1 can be optioned as a sequential (random) or a direct key. The remaining 7 keys (KEY2~KEY8) are used as direct keys exclusively or by mask op- tion as matrix key input (44). • Fast access time: C 117, 100 MHz; 6 ns (83 MHz); • Internal self-timed write cycle • Individual Byte Write Control and Global Write • Clock controlled, registered address, data and control • Pentium™ or linear burst sequence control using MODE input • Five chip enables for simple depth expansion and address pipelining • Common data inputs and data outputs • Power-down control by ZZ input • JEDEC 128-Pin TQFP 14mm x 20mm package • Single +3.3V power supply • Control pins mode upon power-up: C MODE in interleave burst mode C ZZ in normal operation mode These control pins can be connected to GNDQ or VCCQ to alter their power-up state Vth can be expressed as voltage between gate and source when low operating current value is ID = 100 mA for this product. For normal switching operation, VGS (on) requires higher voltage than Vth and VGS (off) requires lower voltage than Vth. (Relationship can be established as follows: VGS (off) < Vth < VGS (on) ) Please take this into consideration for using the device. VGS recommended voltage of 1.5 V or higher to turn on this product. Following the address and acknowledge bit with logic 0 in the read/write bit, the first byte written is the command byte. If the command byte is reserved and therefore not valid, it will not be acknowledged. Only valid command bytes will be acknowledged. |
