OHG • Regensburg, Germany www.osram-os.com • +49-941-202-7178 5 July 5, 2001-14 DC Characteristics at 25 °C Note: 1) D0 to D7 have no pull-up resistors so current is negligible. Pin Assignments and Definitions Parameter Limits Conditions Min. Typ. Max. Units VCC 4.5 5.0 5.5 Volts Nominal ICC (Blank) — 2.5 3.5 mA VCC=5.0 V, A2=1, all other inputs low. ICC 80 LEDs/unit (100% Bright) PD243X PD353X PD443X — 115 145 150 130 165 170 mA mA mA VCC=5.0 V VCC=5.0 V VCC=5.0 V VIL — — 0.8 Volts VCC=4.5 V to 5.5 V VIH 2.0 — — Volts VCC=4.5 V to 5.5 V IIL (except D0 to D7) (1) 25 — 100 µA VCC=4.5 V to 5.5 V, VIN=0.8 V VOL — — 0.4 Volts VCC=4.5 V to 5.5 V VOH 2.4 — — Volts VCC=4.5 V to 5.5 V IOH –8.9 — — mA VCC=4.5 V, VOH=2.4 V IOL 1.6 — — mA VCC=4.5 V, VOL=0.4 V Data I/O Bus Loading — — 100 pF — Clock I/O Bus Loading — — 240 pF — Pin Function Definition 1RD Active low, will enable a processor to read all registers in the display. 2 CLK I/O If CLK SEL (pin 3) is low, then expect an external clock source into this pin. If CLK SEL is high, then this pin will be the master or source into this pin. If CLK SEL is high, then this pin will be the master or source for all other devices which have CLK SEL low. 3 CLKSEL CLOCK SELECT determines the action of pin 2. CLK I/O, see the sec- tion on Cascading for an example. 4 RST Reset. Used to synchronize blinking. Will not clear the display. The reset pulse should be less than 1 ms 5 CE1 Chip enable (active high). 6 CE0 Chip enable (active low). 7 A2 Address input (MSB). 8 A1 Address input. 9 A0 Address input (LSB). 10 GND Ground. Pin Assignments and Definitions (continued) Pin Function Definition 11 WR Write. Active low. If the device is selected, a low on the write input loads the data into memory. 12 D7 Data Bus bit 7 (MSB). 13 D6 Data Bus bit 6. 14 D5 Data Bus bit 5. 15 D4 Data Bus bit 4. 16 D3 Data Bus bit 3. 17 D2 Data Bus bit 2. 18 D1 Data Bus bit 1. 19 D0 Data Bus bit 0 (LSB). 20 VCC Positive power pin. |
