I Mask ROM Address input pins. I The CEn (Chip Enable) input is the device selection and power control for internal Mask ROM array. Whenever CEn goes high, the internal Mask ROM will enter standby (power saving) mode. Otherwise, it is in active mode and the contents of the ROM can be accessed. P Negative power supply input pin. I OEn (Output Enable) is the output control which gates ROM array data onto the data output pins Q7 ~ Q0 in Byte mode (BYTEB pin is at "low" state) or Q15A-1, Q14 ~ Q0 in Word mode (BYTEB pin is at "high" state). O, Mask ROM array Data lower byte outputs drive Q7 ~ Q0 pins during read O, operations (CEn and OEn are "low"). The Q7 ~ Q0 pins stay in high-Z when O, the chip is deselected (CEn high) or when the outputs are disabled (OEn O, high). O, O, O, O, O, Mask ROM data higher byte output pins when Word mode is selected O, (BYTEB is at "high" level) during read operations (CEn and OEn are O, "low"). They will be tri-stated when Byte mode is selected (BYTEB at O, "low" level), the chip is deselected (CEn high), the outputs are disabled O, (OEn high). O, O, O/I, Q15A-1 is Mask ROM MSB Data output pin in Word mode and LSB address pin in Byte mode. P Positive power supply input pin.

AC Electrical Characteristics READ CYCLE: December 8, 2003 Page 6 of 7 V1.1 This specification is subject to change without notice. Please contact sales person for the latest version before use. King Billion Electronics Co., Ltd SF23C3200B There are two ways of accessing the ROM data. The first one is to assert the valid address on the Address Bus, then assert CEn "low" to enable the ROM array. The access time in this mode is specified as tACE. The advantage of this access mode is that power consumption can be lowered. The second access mode keeps the CEn "low" while changes the addresses to access the contents of ROM data. The access time in this way is specified as tAA.
