Product data sheet Rev. 5 — 12 November 2018 32 of 54 NXP Semiconductors PCA85233 Automotive 80 × 4 LCD driver for low multiplex rates [1] LCD outputs are open-circuit; inputs at VSS or VDD; external clock with 50 % duty factor; I2C-bus inactive. [2] The I2C-bus interface of PCA85233 is 5 V tolerant. [3] Not tested, design specification only. [4] Outputs measured individually and sequentially. LCD outputs V O output voltage variation on pins BP0 to BP3; Cbpl = 35 nF 100 - +100 mV on pins S0 to S79; Csgm = 5 nF 100 - +100 mV RO output resistance VLCD = 5 V on pins BP0 to BP3 [4] -1.5 10 k on pins S0 to S79 [4] -6.0 13.5 k Table 20. Static characteristics …continued VDD = 1.8 V to 5.5 V; VSS = 0 V; VLCD = 2.5 V to 8.0 V; Tamb = 40 C to +105 C; unless otherwise specified. Symbol Parameter Conditions Min Typ Max Unit Conditions: VDD = 5.5 V; VLCD =8V; Tamb =27 C; all RAM filled with 0. (1) IDD(LCD). (2) IDD. Fig 21.
