3 / 72 page  2004 Mar 05 3 Philips Semiconductors Product specification (67 + 1) × 102 pixels matrix LCD driver PCF8813 1 FEATURES • Single-chip LCD controller or driver • 67 row + 1 icon row, 102 column outputs (the icon row is available twice to allow icons to be displayed at the top or at the bottom of the display) • Very low power consumption, optimized for battery operated systems • On-chip: – Display data RAM 68 × 102 bits – Configurable voltage multiplier ( × 5, × 4, × 3 and × 2) generating highly accurate VLCD and includes booster capacitors (external VLCD is also possible) – Temperature compensation of VLCD with four selectable temperature coefficients – Generation of intermediate LCD bias voltages – Highly-accurate built-in oscillator requiring no external components (an external clock is also possible) • High integration level resulting in minimum number of external capacitors and resistors • Selectable 8-bit parallel interface, 3-line or 4-line Serial Peripheral Interface (SPI), 3-line serial interface and high-speed I2C-bus interface • External reset input • CMOS compatible inputs • Mux rates: 1 : 9 to 1 : 65 in steps of 8 and1:68 • Logic supply voltage range 1.7 to 3.3 V • High voltage generator supply voltage range 2.4 to 4.5 V • Display supply voltage range 3.0 to 9.0 V • One Time Programmable (OTP) VLCD trimming • Horizontal and vertical mirroring • Status read which allows chip recognition and content checking of some registers • Start address line which allows, for instance, scrolling of the displayed image • Programmable display RAM pointers for various display sizes • Slim chip layout optimized for chip-on-glass applications • Operating temperature range −40 to +85 °C • Very close tolerance on VLCD and frame frequency for excellent optical performance • Support for LCD cell tolerance compensation of VLCD by OTP storage. 2 APPLICATIONS • Telecom equipment • Portable instruments • Point of sale terminals. 3 GENERAL DESCRIPTION The PCF8813 is a low power CMOS LCD controller driver designed to drive a graphic display of 67 rows and 102 columns plus an icon row of up to 102 symbols. All necessary functions for the display are provided in a single chip, including on-chip generation of the LCD supply and bias voltages, resulting in a minimum of external components and low power consumption. The PCF8813 can interface to microcontrollers via a parallel, serial or I2C-bus interface. 4 ORDERING INFORMATION TYPE NUMBER PACKAGE NAME DESCRIPTION VERSION PCF8813U/2DA/2 − chip with bumps in tray for COG − |
