ST7567S-G4 Overview
A dot matrix LCD controller/driver such as the ST7567S-G4 sits in the system hierarchy between a microcontroller host (MPU) and the physical liquid-crystal glass. It accepts graphics commands from the MPU, stores pixel data in DDRAM, and continuously refreshes the panel through segment and common drivers while generating the bias voltages required for proper pixel RMS drive. Without such a controller, the MPU would need to multiplex all 65 commons and 132 segments in software, which is impractical for low-power portable designs.
Key features include a built-in oscillation circuit that eliminates the need for an external clock, a low-power power circuit that derives all internal analog supplies without external DC-DC conversion, and a wide logic supply range. The device supports multiple duty modes, partial-display, standby current in the single-digit microamp range, and is widely used in monochrome graphic modules from 128x32 up to 132x65 pixel resolution.
Architecture-wise the chip integrates a high-voltage analog block for generating V0-V4 LCD biases, an 8-bit MPU interface (6800/8080 parallel or 4-wire SPI), and on-chip character/icon RAM. Hardware reset and command-set extensions (set page, set column, contrast control via the electronic-volume command, display ON/OFF, inverse display, all-points-ON) follow the common ST7565/ST7567 family convention used on most graphic COG modules on the market.
Typical applications include 128x64 graphic LCD modules for instrumentation and metering, 132x65 graphical panels for handheld POS and industrial HMIs, monochrome STN displays for white goods and consumer electronics, and small dot-matrix COG panels in wearable devices. The ultra-low standby current also makes the chip attractive for battery-powered IoT indicators. Designers choose this IC because it removes the need for an external bias generator or oscillator, dramatically reducing BOM and PCB area in compact module designs.
When designing with the ST7567S-G4, careful attention must be paid to bias and contrast-voltage component selection (the external V0 capacitor network dominates the visual contrast), and to reset timing during MPU initialization. The same datasheet-level command set shared by the ST7565/ST7567 family means many existing U8g2 and Adafruit library examples will work unchanged. This page consolidates distributor pricing, compatible alternate COG/TCP LCD controllers, and engineering notes beyond what is contained in the manufacturer datasheet.

Typical Applications
ST7567S-G4 is suitable for 6 applications: 128x64 Graphic COG LCD Module, Handheld POS and Industrial HMI Displays, Wearable Health-Monitoring Devices, Consumer Appliance Indicators, Battery-Powered IoT Status Indicators, Industrial Metering and Sensor Module.
128x64 Graphic COG LCD Module
The ST7567S-G4 is the industry-standard controller for 128x64 monochrome graphic COG LCD modules used in serial-port instrument displays, hobbyist Arduino shields and industrial meters. Its 65 x 132-dot DDRAM covers the 128x64 logical area with reserve columns for COM bias and icon areas, while the on-chip charge pump generates the V0-V4 bias ladder so the panel needs only two external pump capacitors. Most 128x64 COG modules on the market (Newhaven NHD-C12864xxxx series, BuyDisplay ERC12864) ship pre-programmed with the ST7567S as their controller, reducing firmware-development time. Design tip: keep the VOUT capacitor as close as possible to the chip pad for minimum ripple on V0 and best contrast uniformity.

Handheld POS and Industrial HMI Displays
Portable handheld POS terminals and industrial HMI panels benefit from the ST7567S-G4's low standby current (microamps range, allowing battery life in handheld devices) and built-in oscillator that suppresses component count on the main PCB. The 132 x 65 panel resolution supports six 16-pixel-tall or eight 8-pixel-tall text rows, sufficient for receipt-preview line counts in POS units. Designers typically drive the chip via 4-wire SPI from a Cortex-M0 or Cortex-M4 host at 1-2 MHz clock; the SPI init sequence completes within approximately 50 ms, which is acceptable for cold-boot timing. The chip is AOI-compatible and supports partial display-on mode to refresh only the changing area, saving more power in standby HMI states.
Recommended
Wearable Health-Monitoring Devices
Wearable health monitors and continuous glucose sensors use small 128x48 or 132x49 monochrome STN panels driven by the ST7567S-G4 because of its single-IC footprint, low standby current, and ability to operate from coin-cell or rechargeable Li-coin supplies as low as 2.7 V. The built-in contrast-control electronic-volume command (EV) lets firmware fine-tune pixel darkness to match temperature shifts and battery droop without a separate contrast DAC. Designers also leverage the chip's all-points-ON (APON) mode to drive the entire panel during self-test at device power-up, with no extra firmware overhead. Typical CoG integration partners quote 1.6 inch 128x64 modules at sub-USD 5 in 1k quantities for this application.
Recommended
Consumer Appliance Indicators
Domestic white-goods, microwave ovens, and small kitchen appliances use 132 x 65 panels based on the ST7567S-G4 to display user menus, cooking programs, and diagnostics. The wide 2.7 V to 5.5 V VDD range lets the chip run from a 3.3 V linear regulator in mains-appliance designs (or be powered from the same 5 V rail as the host MCU), reducing BOM cost. The on-chip oscillator saves one external crystal or ceramic resonator part, a meaningful saving in cost-sensitive consumer SKUs. Designers typically use the inverter-display and horizontal-mirror commands to handle either mounting orientation of the display glass without mechanical re-spin.
Recommended
Battery-Powered IoT Status Indicators
Battery-powered IoT sensor nodes, BLE beacons, and LoRaWAN end devices need a low-current visual readout for status diagnostics, and the ST7567S-G4 fits that role with its microamp-range standby and partial-display mode. When the radio is idle, the chip can refresh only the 16 x 16 status icon to draw under 50 uA total panel current, extending battery life in remote deployments. The 4-wire SPI interface makes it suitable for connection to ESP32, nRF52, and STM32WL hosts via DMA-driven packet writes. Designers also appreciate that the same driver as the ST7565 can be reused, which is why U8g2 and Adafruit include ST7567 examples.
Recommended
Industrial Metering and Sensor Module
Industrial panel meters, ultrasonic flow sensors, and pressure transducers commonly ship with a ST7567S-G4-driven 128x64 LCD that displays process variables and engineering units simultaneously. The chip's -40 C to +85 C industrial operating-temperature grade and on-chip bias stability across temperature make it suitable for outdoor or factory-floor installations where ambient swings are wide. The electronic-volume command enables the host to compensate contrast for cold-temperature pixel darkening, eliminating factory contrast-trim potentiometers. Designers also benefit from the 25 embedded commands in the datasheet that allow OEMs to define custom commands for flow-totalization counters and peak-tracking displays.

- Wider 2.7 V to 5.5 V logic supply (vs Epson SED1565)
Design Notes
Estimated: The COG bonding pads of the ST7567S-G4 require carefully matched trace widths in the panel-glass routing; the datasheet specifies a minimum bump-pad pitch of 35 micron and recommends keeping adjacent SEG/COM traces far enough apart to avoid crosstalk-induced ghost dots at high contrast. Designers working with this die for the first time should reference the Sitronix app-note figures on glass routing when laying out the ITO mask. Plan for at least 0.5 mm bezel isolation between the die bumps and the active LCD area to avoid insulation breakdown.
The V0-V4 bias ladder stability depends directly on the external pump capacitor values (typically 1 uF X5R ceramic on C1+/C1-/C2+/C2-). Use low-ESR ceramics and place them within 5 mm of the bump pads to maintain ripple under 30 mV - otherwise visible pixel-darkening flicker occurs at 1/65 duty. Verify the electronic-volume value (the EV command range 0x00-0x3F) at room temperature and across the -40 C to +85 C industrial range to keep contrast consistent for end users.
When driving the ST7567S-G4 over 4-wire SPI from a 3.3 V MCU at clock speeds above 1 MHz, add 10-100 ohm series resistors on SCLK, SI, /CS, /RES lines to slow edge rates and reduce EMI - the chip is purely a slave and tolerates slower edges without issue. Keep the SPI traces short, with ground-return underneath, and provide 0.1 uF decoupling on VDD adjacent to the chip. Failed init at lower VDD often points to a missed reset-release timing: maintain at least 1 ms between VDD rising above 2.7 V and the first SPI command.
Compliance Information
RoHS compliant per Newhaven Display and BuyDisplay product pages. The -40 C to +85 C industrial operating temperature grade is the standard option; AEC-Q100 not applicable for a controller/display-grade die that is not part of the safety-critical signal chain.
