µPD23C16000BL
16M-BIT MASK-PROGRAMMABLE ROM
2M-WORD BY 8-BIT (BYTE MODE) / 1M-WORD BY 16-BIT (WORD MODE)
Description
The µPD23C16000BL is a 16,777,216 bits mask-programmable ROM. The word organization is selectable (BYTE
mode : 2,097,152 words by 8 bits, WORD mode : 1,048,576 words by 16 bits).
The active levels of OE (Output Enable Input) can be selected with mask-option.
The µPD23C16000BL is packed in 48-pin PLASTIC TSOP(I) and 44-pin PLASTIC SOP.

Input
The pin for switching WORD mode and BYTE mode.
High level : WORD mode (1M-word by 16-bit)
Low level : BYTE mode (2M-word by 8-bit)
Input
Address input pins.
A0 to A19 are used differently in the WORD mode and the BYTE mode.
WORD mode (1M-word by 16-bit)
A0 to A19 are used as 20 bits address signals.
BYTE mode (2M-word by 8-bit)
A0 to A19 are used as the upper 20 bits of total 21 bits of address signal.
(The least significant bit (A−1) is combined to O15.)
Output Data output pins.
O0 to O7, O8 to O14 are used differently in the WORD mode and the BYTE mode.
WORD mode (1M-word by 16-bit)
The lower 15 bits of 16 bits data outputs to O0 to O14.
(The most significant bit (O15) combined to A−1.)
BYTE mode (2M-word by 8-bit)
8 bits data outputs to O0 to O7 and also O8 to O14 are high impedance.
Output, Input O15, A−1 are used differently in the WORD mode and the BYTE mode.
WORD mode (1M-word by 16-bit)
The most significant output data bus (O15).
BYTE mode (2M-word by 8-bit)
The least significant address bus (A−1).
Input
Chip activating signal.
When the OE is active, output states are following.
High level : High-Z
Low level : Data out
Input
Output enable signal. The active level of OE is mask option. The active level of OE
can be selected from high active, low active and Don’t care at order.
− Supply voltage
GND
− Ground
NC − Not internally connected. (The signal can be connected.)
