3 / 33 page CY14B104K, CY14B104M Document #: 001-07103 Rev. *S Page 3 of 33 Pinouts Figure 1. Pin Diagram - 44-PIn and 54-Pin TSOP II Table 1. Pin Definitions Pin Name I/O Type Description A0 – A18 Input Address inputs. Used to select one of the 524,288 bytes of the nvSRAM for x8 configuration. A0 – A17 Address inputs. Used to select one of the 262,144 words of the nvSRAM for x16 configuration. DQ0 – DQ7 Input/Output Bidirectional data I/O lines for ×8 configuration. Used as input or output lines depending on operation. DQ0 – DQ15 Bidirectional data I/O lines for ×16 configuration. Used as input or output lines depending on operation. NC No connect No connects. This pin is not connected to the die. WE Input Write Enable input, Active LOW. When selected LOW, data on the I/O pins is written to the specific address location. CE Input Chip Enable input, Active LOW. When LOW, selects the chip. When HIGH, deselects the chip. OE Input Output Enable, Active LOW. The active LOW OE input enables the data output buffers during read cycles. Deasserting OE HIGH causes the I/O pins to tristate. BHE Input Byte High Enable, Active LOW. Controls DQ15 - DQ8. BLE Input Byte Low Enable, Active LOW. Controls DQ7 - DQ0. Xout Output Crystal connection. Drives crystal on startup. Xin Input Crystal connection. For 32.768 kHz crystal. VRTCcap Power supply Capacitor supplied backup RTC supply voltage. Left unconnected if VRTCbat is used. VRTCbat Power supply Battery supplied backup RTC supply voltage. Left unconnected if VRTCcap is used.
