Product details
Overview
HDMI2C2-5F2 from STMicroelectronics is an integrated ESD protection and bidirectional DDC signal conditioning IC for HDMI sink applications, supporting HDMI 1.4/2.0/2.1 compliance with 8 kV contact ESD protection (IEC 61000-4-2 Level 4), dynamic pull-up on SDA/SCL lines, and 1.8 V–3.63 V ASIC-side voltage translation. It operates across –40 °C to +85 °C and enables power optimization via ENABLE_IC sensing of 5 V presence.
For engineers reviewing the HDMI2C2-5F2 datasheet, HDMI2C2-5F2 pinout, HDMI2C2-5F2 application, or HDMI2C2-5F2 equivalent, key selection criteria include DDC bus capacitance handling (750 pF max), I²C-level bidirectional level shifting, backdrive protection, and WLCSP-10 footprint constraints in space-constrained consumer electronics designs.
Technical Context
The HDMI2C2-5F2 implements two fully compliant I²C bidirectional buffers (SDA/SCL) with integrated dynamic pull-up circuitry synchronized to driver edges, enabling reliable communication over long or high-capacitance HDMI cables (up to 750 pF). It performs voltage translation between 5 V cable-side and 1.8–3.63 V ASIC-side logic levels while maintaining I²C timing compliance (TRISE_BUS ≤ 500 ns at 750 pF).
Its ENABLE_IC pin provides dual-function operation: sensing 5 V_IN presence (VTH_EN = 30–70% VDD_IC) and actively disabling the DDC block to reduce quiescent current (IQS_IC_OFF = 4–8 µA). Backdrive protection blocks reverse current flow from the HDMI connector when ENABLE_IC = 0, isolating the ASIC during hot-plug or standby conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection | ±8 kV contact (IEC 61000-4-2 Level 4) on SDA/SCL/CEC/HPD/5V_IN pins - ensures robustness against user-handling ESD events at HDMI connector. |
| DDC Bus Capacitance Drive | Supports up to 750 pF total load (cable + connector) - meets HDMI 1.4 CTS requirement and enables compatibility with long/poor-quality cables. |
| Rise Time (TRISE_BUS) | ≤500 ns at 750 pF load - maintains I²C signal integrity and HDMI CTS compliance without external active boosters. |
| Voltage Translation Range | ASIC side: 1.62–3.63 V (VDD_IC); Cable side: 4.7–5.3 V (5V_IN) - supports low-voltage HDMI ASICs down to 1.8 V logic. |
| Enable Function Threshold | V5V_ON = 3.5–4.1 V; ENABLE_IC output reflects 5V_IN status and controls DDC block enable/disable - enables system-level power gating. |
| Input Capacitance (CIN_DDC) | 25–30 pF - contributes minimally to DDC bus loading and remains independent of ASIC capacitance due to internal decoupling architecture. |
Pinout & Package
Package: 500 µm pitch WLCSP with 10 bumps (ECOPACK-compliant, flip-chip mounting). Natural PCB routing enabled by symmetric bump layout and minimal footprint (≈0.8 mm × 1.2 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 SCL | DDC clock output (HDMI cable side) | Bidirectional I²C clock line with dynamic pull-up, ESD-protected, 5 V tolerant. |
| B1 SDA | DDC data output (HDMI cable side) | Bidirectional I²C data line with dynamic pull-up, ESD-protected, 5 V tolerant. |
| C1 5V_IN | +5 V power input (HDMI connector side) | Supplies cable-side circuitry; used for ENABLE_IC sensing and VDD_5V_ON threshold detection. |
| A2 CEC | Consumer Electronics Control output (cable side) | Bi-directional CEC line support with ESD protection; shares same protection architecture as DDC lines. |
| C2 HPD | Hot Plug Detect input (cable side) | High-impedance input monitoring HDMI connector plug-in status; referenced to 5V_IN. |
| A3 SDA_IC | DDC data input (ASIC side) | Low-voltage (1.8–3.63 V) I²C data interface to HDMI receiver ASIC; open-drain compatible. |
| C3 ENABLE_IC | Enable/sense control I/O | Dual-role pin: outputs 5V_IN presence flag and accepts logic-level enable command to disable DDC block. |
| A4 SCL_IC | DDC clock input (ASIC side) | Low-voltage (1.8–3.63 V) I²C clock interface to HDMI receiver ASIC; open-drain compatible. |
| C4 VDD_IC | ASIC-side power supply | Provides power to internal level shifters and logic; range 1.62–3.63 V; requires local 100 nF decoupling. |
| B2 GND | Ground reference | Common return path for all internal circuits; must be connected to low-impedance system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Pull-Up on DDC Lines | Synchronized short-duration current boost during rising edge reduces TRISE_BUS to ≤500 ns at 750 pF - eliminates need for external active termination. |
| Backdrive Protection | Active isolation of SDA/SCL lines when ENABLE_IC = 0 prevents reverse current injection into ASIC during hot-unplug or 5V_IN absence - protects sensitive HDMI receiver I/O. |
| Integrated DDC Decoupling | Capacitive decoupling between ASIC and connector sides ensures stable signal translation without external capacitors - simplifies layout and reduces BOM count. |
| Enable-Controlled Power Gating | Reduces IQS_IC to 4–8 µA in disabled state - enables system-level standby mode without sacrificing DDC responsiveness on wake-up. |
| WLCSP-10 Footprint Optimization | 0.8 mm × 1.2 mm area with 500 µm bump pitch - enables placement directly adjacent to HDMI connector on ultra-thin PCBs (e.g., tablets, game consoles). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI sink DDC protection and level-shifting applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPD12S016 | Single-channel DDC protection only; no ENABLE_IC function; requires external 5 V regulator; higher input capacitance (45 pF). | Lacks dynamic pull-up and backdrive blocking - limited to short-cable (<3 m), low-capacitance applications. | Select when cost sensitivity outweighs cable robustness requirements and system lacks 5 V sensing capability. |
| NXP PUSB3BM | Supports HDMI 2.1 DDC but lacks integrated dynamic pull-up; relies on external RC networks for rise-time control; no ENABLE_IC pin. | Requires additional passive components and layout area; not qualified for HDMI 2.0 CTS out-of-box. | Choose only if existing design already uses NXP ecosystem and can accommodate added BOM complexity for timing tuning. |

FAQ
What is the maximum cable capacitance HDMI2C2-5F2 can drive on the DDC bus?
HDMI2C2-5F2 is specified to drive up to 750 pF total DDC bus capacitance - matching the HDMI 1.4/2.0 specification limit for combined cable and connector loading. This value is verified with TRISE_BUS ≤ 500 ns under worst-case conditions (VDD_IC = 1.8 V, CBUS = 750 pF, RUP = 2 kΩ // 47 kΩ), eliminating need for external active termination.
How does the ENABLE_IC pin function in both sensing and control modes?
ENABLE_IC serves dual roles: as an output, it asserts high (VDD_IC) when 5V_IN exceeds VDD_5V_ON (3.5–4.1 V), indicating valid HDMI power; as an input, driving it low disables the DDC block and reduces IQS_IC to 4–8 µA. Both functions operate independently - e.g., ENABLE_IC can be forced low even with 5V_IN present to enter ultra-low-power mode.
Does HDMI2C2-5F2 support CEC and HPD signals in addition to DDC?
Yes - HDMI2C2-5F2 integrates protection and routing for CEC (pin A2) and HPD (pin C2) alongside SDA/SCL. CEC is bidirectional with ESD protection matching DDC lines; HPD is a high-impedance input referenced to 5V_IN, enabling hot-plug detection without additional level-shifting components.
What is the recommended PCB layout practice for the WLCSP-10 package?
Use the manufacturer-provided footprint (DS12666 Fig. 12) with 0.5 mm pitch, non-solder-mask-defined pads, and thermal relief vias under the die area. Place a 100 nF ceramic capacitor between VDD_IC and GND within 2 mm of the package. Route SDA/SCL traces differentially with controlled impedance (≈100 Ω) and avoid stubs longer than 3 mm to preserve signal integrity.
