PAL20P8C Datasheet
PAL20P8C Price Ripple current, less than 100 mQ equivalent series resistance (ESR), and temperature are major considerations when selecting input capacitors. Unlike polymer-tantalum capacitors, regular tantalum capacitors are not recommended for the input bus. These capacitors require a recommended minimum voltage rating of 2 x ~ (maximum DC voltage + AC ripple). This is standard practice to ensure reliability. There were no tantalum capacitors, with sufficient voltage rating, found to meet this requirement. When the operating temperature is below OoC, the ESR of aluminum electrolytic capacitors increases. For these applications Os-Con, polymer-tantalum, and polymer-aluminum types should be considered. PAL20P8C on stock
WEL: Write Enable Latch-Volatile The WEL bit controls the access to the CCR and mem- ory array during a write operation. This bit is a volatile latch that powers up in the LOW (disabled) state. While the WEL bit is LOW, writes to the CCR or any array address will be ignored (no acknowledge will be issued after the Data Byte). The WEL bit is set by writing a "1" to the WEL bit and zeroes to the other bits of the Status Register. Once set, WEL remains set until either reset t0 0 (by writing a "0" to the WEL bit and zeroes to the other bits of the Status Register) or until the part pow- ers up again. Writes to WEL bit do not cause a non-vol- atile write cycle, so the device is ready for the next operation immediately after the stop condition. |
