ST7567A Visão geral
A dot matrix LCD controller/driver is a category of display IC that combines an MPU interface, a bit-mapped Display Data RAM (DDRAM), character/graphic rendering logic, and high-voltage segment/common drivers on one piece of silicon. The ST7567A belongs to the ST7565/ST7567 family of mono STN-LCD driver ICs from Sitronix, sitting within the broader industrial display-driver IC product line that maps to discrete, character, and graphic passive-matrix display modules.
Key features include 8580-bit DDRAM (132x65), selectable bias levels (1/65, 1/49, 1/33, 1/55 duty), a 4X booster for LCD bias generation, and wide operating temperature support. The device can drive a graphics display up to 132x65 pixels with on-chip RAM allowing direct mapping from display data without external frame buffer memory.
The architecture uses mixed-signal HVCMOS technology that integrates analog charge pumps, an internal oscillator, and digital logic. The high segment count (132) is achieved through on-chip latches and bias generation circuits, while the built-in booster reduces the discrete BOM by removing the need for an external VEE supply.
Typical applications include mono graphic LCD modules (COG/TCP packages), industrial instrumentation displays, point-of-sale terminals, medical device user interfaces, white-goods control panels, and consumer audio/visual equipment displays. The internal bias-generation and built-in oscillator make it particularly suited to cost-sensitive, low-power mono graphic modules.
When designing with the ST7567A, consider the on-chip booster limitations for very large panels and ensure MPU interface voltage compatibility. Reset timing should be observed per the Sitronix datasheet to avoid display initialization errors.

Aplicações típicas
ST7567A é adequado para 6 aplicaçãos: Mono Graphic LCD Modules (128x64 / 132x64), Industrial Control Panels, Point-of-Sale (POS) Terminals, Medical Device User Interfaces, Consumer White-Goods Control Panels, Audio/Visual Equipment Displays.
Mono Graphic LCD Modules (128x64 / 132x64)
The ST7567A is the standard controller/driver IC for mono graphic LCD modules in the 128x64 and 132x64 pixel format, the most common format for low-cost graphic displays used in industrial control panels. Its 132x65 matrix with 8580-bit DDRAM maps directly to common graphic module resolutions without external frame buffer memory. MPU interface flexibility (8-bit parallel or 4-wire SPI) allows it to connect to nearly any microcontroller, including low-pin-count STM32 and PIC parts. Placed between the host MCU and the LCD glass via COG bonding, the ST7567A generates all segment and common drive signals internally. The on-chip booster eliminates the external VEE supply, reducing BOM by one DC-DC converter or charge pump per module.

Industrial Control Panels
The ST7567A drives the graphic LCDs in industrial HMI panels, machine control interfaces, and process instrumentation displays where high-resolution mono graphics must be readable under varied lighting. Its 132x65 resolution supports icons, status bars, and multi-line text without external memory, while the on-chip bias generation survives the wide operating temperatures found in factory environments. Compared to character-only LCD controllers, the ST7567A enables custom graphical status icons for fault states and live process readings. The SPI/parallel MPU interface lets engineers pair it with low-cost industrial MCUs across the supply chain. Sitronix datasheet industrial-grade operating temperature support also makes the ST7567A a reliable choice for 24/7 industrial HMI displays.
Recomendado
Point-of-Sale (POS) Terminals
The ST7567A is widely used in low-end POS terminals, barcode scanners, and receipt-printer companion displays where a small mono graphic LCD shows transaction status, item names, and totals. Its on-chip 8580-bit DDRAM eliminates the external SRAM typical of higher-end controllers, keeping the BOM cost low enough for sub-$50 POS hardware. The 4-wire SPI interface allows the host MCU to update the display rapidly during bar-code scanning without stalls. Combined with the on-chip booster, the ST7567A reduces POS module power consumption to a level suitable for battery-powered mobile POS terminals per typical Sitronix application notes.
Recomendado
Medical Device User Interfaces
The ST7567A drives mono graphic displays in medical devices such as blood-pressure monitors, glucose meters, infusion pumps, and handheld diagnostic readers where a small graphic display is needed for readouts, menus, and trend graphs. The 132x65 resolution supports readable numeric displays and simple iconography while the on-chip bias generation improves EMI immunity compared to designs with external charge pumps. Its compatibility with both 8-bit parallel and 4-wire SPI allows pairing with medical-grade MCUs across manufacturers. The Sitronix datasheet's operating-temperature range covers typical medical device environments from clinic to home-care settings.

Consumer White-Goods Control Panels
The ST7567A is the controller inside the graphic LCDs found on washing machines, microwave ovens, dishwashers, and air-conditioner control panels, where a small mono graphic LCD replaces older 7-segment or 14-segment character displays. Its on-chip booster and oscillator allow the panel to operate from a single MCU supply, simplifying the switching power supply. The 132x65 resolution supports multi-language status icons, timer readouts, and fault indicators without extra logic. Its low power consumption per the Sitronix datasheet suits always-on standby modes common in white-goods UI panels.
Recomendado
Audio/Visual Equipment Displays
The ST7567A drives the mono graphic displays on consumer A/V gear including portable radios, effect-pedal controllers, MIDI controllers, equalizers, and small-format mixing consoles. Its 132x65 resolution supports segmented level meters, parameter readouts, and menu-driven A/V configuration screens, while the 4-wire SPI interface allows audio DSPs and MCUs to drive the display with minimal pin overhead. The on-chip booster reduces BOM cost, important for consumer-grade pricing. Sitronix datasheet figures show low quiescent power suitable for always-on A/V front-panel displays.

Notas de projeto
The ST7567A is supplied primarily as a bare die for Chip-on-Glass (COG) bonding directly to the LCD glass. PCB layout for COG modules follows the bonding-pad diagram in the Sitronix datasheet, not a conventional IC pinout. Verify the pad numbering, segment/common routing, and the MPU interface pads (SCL, SI, CS, A0, /RES, /C86, P/S) against the COG layout before tape-out. ITO traces on the glass must be kept under the maximum sheet-resistance limit per the Sitronix datasheet.
Connect a 1uF X7R bypass capacitor directly to the ST7567A VDD and VSS pads, placed as close to the bonding pads as the glass layout allows. The internal booster requires this capacitor for stable operation per the Sitronix datasheet; undersizing it leads to display flicker and degraded contrast. For SPI-driven designs, the MPU supply should match VDD; for 8-bit parallel, level-shifters are required if the MPU runs at lower voltage.
The ST7567A's parallel interface (8080 or 6800 mode) is sensitive to bus timing on long MPU traces. Estimated: at bus speeds above 1 MHz on an 8-bit parallel interface, route data and control traces impedance-matched and length-matched within 50 mils. Series damping resistors of 33 ohm near the MPU pins help reduce ringing on long flex-cable or board-to-board connections to the display module per the Sitronix MPU timing parameters.
Resist the temptation to assume the ST7567A has a discrete-package pinout - it is sold as a COG die with a bonding-pad diagram. Designers must obtain the Sitronix datasheet pad map (and the LCD module's COG layout) before integrating the ST7567A into a new display. The /RES pin must be toggled at power-up per the Sitronix power-on sequence, or the display will appear blank until a software-init reset is issued.
