Product details
Overview
MAX6960AMH+D from Maxim Integrated is a 4-wire serially interfaced, cathode-row LED display driver for 8 × 8 matrix displays. It supports two monocolor or one RGY (red/green/yellow) display with 2- or 4-step pixel-level intensity control, 256-step global panel brightness, and analog/digital digit-by-digit current calibration. Designed for indoor signage and message boards, it operates from 2.7V–3.6V and delivers up to 40mA peak segment current per digit.
For engineers reviewing the MAX6960AMH+D datasheet, MAX6960AMH+D pinout, MAX6960AMH+D application, or MAX6960AMH+D equivalent, key selection considerations include its 44-pin MQFP package, dual-digit RGY support, open/short LED fault detection, local 3-wire address bus for daisy-chained configurations, and compatibility with 20MHz high-speed serial interface timing.
Technical Context
The MAX6960AMH+D implements frame-modulated pixel intensity using a 12-frame superframe to deliver arithmetic (off, 1/3, 2/3, full) or geometric (off, 1/4, 1/2, full) 4-level per-pixel control. Its architecture enables memory-mapped display planes across up to 256 daisy-chained drivers via ADDIN/ADDOUT/ADDCLK, with automatic address allocation and global command broadcast.
It features dual RISET pins (RISET0/RISET1) enabling independent 20mA or 40mA peak segment current programming per digit-either fixed via GND/open or adjustable via external resistors-and integrates slew-rate-limited segment drivers to reduce EMI while supporting burst white mode and plane-switching intervals from 63Hz to one change per 63 seconds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7V to 3.6V - Enables direct operation from standard 3.3V logic rails with minimal headroom loss across output stages. |

Pinout & Package
MAX6960AMH+D uses a 44-pin MQFP (Metric Quad Flat Package) with exposed pad (EP), requiring connection of EP to GND for thermal and electrical integrity. The package supports surface-mount assembly and provides 16 anode column drivers (COL1–COL16), 8 cathode row sinks (ROW1–ROW8), and dedicated address/data bus pins for multi-driver synchronization.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ROW1–ROW8 | Cathode sink outputs | Drive display rows by sinking up to 750mA total; enable multiplexed scanning of 8×8 matrices. |
| COL1–COL16 | Anode source outputs | Source up to 48mA total; drive 16 columns across two monocolor digits or red/green sub-arrays of RGY digit. |
| RISET0 / RISET1 | Digit current setting inputs | Set digit 0 or digit 1 segment current to 20mA (open) or 40mA (GND); enable resistor-based fine-tuning between values. |
| ADDIN / ADDOUT / ADDCLK | Local 3-wire address bus | Enable automatic memory map allocation across daisy-chained drivers; ADDOUT doubles as plane-change interrupt output. |
| CS / DIN / CLK / DOUT | 4-wire serial interface | Supports global command broadcast and individual register access; DOUT is tri-state for bus sharing. |
Key Features
| Feature | Design Value |
|---|---|
| Digit-by-digit current calibration | Analog (RISET resistors) and digital (256-step scaling) adjustment per digit enables batch-to-batch LED color matching on RGY panels. |
| Multiplane animation engine | Hardware-managed plane switching from 63Hz to one frame per 63s eliminates software timing dependency during display updates. |
| Slew-rate-limited drivers | Controlled ∆ISEG/∆t = 30mA/µs reduces EMI and avoids supply rail collapse during fast column switching. |
| Global command broadcast | Single write operation synchronizes intensity, shutdown, or plane select across all interconnected MAX6960AMH+D devices. |
| LED open/short detection | Automatically identifies failed segments and reports status via fault register-no external sensing circuitry required. |
Applications
| Indoor Message Boards | Gaming Machine Displays |
|---|---|
Use Scenario: Dynamic text and icon updates on wall-mounted or kiosk-based information panels in retail, transit, or facility environments. IC Role / Device Role / Timing Role: Primary LED matrix controller managing 8×8 RGY pixels with real-time intensity grading and fault-aware refresh cycles. Use Value: 256-step global PWM enables ambient light-adaptive brightness; built-in plane switching simplifies scrolling animation without CPU intervention. |

Use Scenario: Front-panel status indicators, channel meters, and menu navigation elements on AV receivers, mixers, and studio monitors. IC Role / Device Role / Timing Role: Low-power display controller driving small-format monocolor 8×8 digits with precise intensity gradation and zero-software-timing overhead. Use Value: Shutdown mode draws only 600µA while retaining full display memory-ideal for standby-aware consumer electronics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LED display driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6962AMH+ | Supports monocolor or RGY displays with 2- or 4-step intensity; lacks RGY-specific configuration bits (C bit fixed at 0) and excludes RGB capability. | Optimized for monocolor-only panels where RGY color mixing is unnecessary; no RGY memory mapping flexibility. | Select MAX6962AMH+ when driving single-color signs with identical intensity requirements but lower firmware complexity. |
| MAX6961AMH+ | Supports monocolor or RGY with 2-step intensity only; PI bit fixed at 0 disables 2-bits-per-pixel mode and limits display memory to 4 planes of 16 bytes. | Suitable for basic on/off or dual-intensity messaging-insufficient for multi-shade RGY graphics or smooth fades. | Choose MAX6961AMH+ for cost-sensitive, low-complexity applications where 4-level per-pixel control is not required. |
Compared with MAX6962AMH+ and MAX6961AMH+, the MAX6960AMH+ uniquely supports full RGY 2-bits-per-pixel operation with configurable C/PI bits, enabling 16-color rendering and flexible memory mapping-making it the only option among the three for advanced RGY graphic signage requiring both color fidelity and animation depth.

FAQ
What display configurations does the MAX6960AMH+D support?
The MAX6960AMH+D supports two monocolor 8×8 matrix displays or one RGY 8×8 matrix display using its 8 cathode-row and 16 anode-column drivers. It enables 2- or 4-step per-pixel intensity control and 256-step global panel brightness. Configuration is set via the PI and C bits in the global panel configuration register, allowing flexible mapping for red/green sub-arrays in RGY mode.
How does the MAX6960AMH+D handle LED fault detection?
The MAX6960AMH+D performs automatic open-circuit and short-circuit detection across all 128 segments (8 rows × 16 columns). Detected faults are reported in the device's fault status register and can trigger an interrupt via the ADDOUT pin when used in daisy-chained configurations. No external components or host polling are required for basic fault reporting.
Can the MAX6960AMH+D drive RGB displays directly?
No, the MAX6960AMH+D cannot drive standard RGB displays directly due to blue LED forward voltage requirements (~3.5V–4.5V), exceeding its 2.7V–3.6V supply range. However, it can serve as the graphics controller for RGB panels when paired with external pass transistors-retaining all features including pixel-level intensity control and fault detection as described in Figure 17 of the datasheet.
What is the function of the RISET0 and RISET1 pins on the MAX6960AMH+D?
RISET0 and RISET1 configure the peak segment current for digit 0 and digit 1 independently: grounding selects 40mA, leaving open selects 20mA, and connecting via resistor enables analog trimming between those values. This allows per-digit current calibration for color matching on RGY displays or efficiency optimization across varying LED batches.
How does the MAX6960AMH+D manage display memory across multiple devices?
The MAX6960AMH+D uses a local 3-wire address bus (ADDIN/ADDOUT/ADDCLK) to automatically allocate contiguous memory map addresses across up to 256 daisy-chained devices. This allows the host to treat the entire panel as unified display memory planes-enabling seamless scrolling, animation, and global commands without manual address calculation or per-device register writes.
