It8995e — 128 Datasheet
Because the IT8995E-128 utilizes a 128-pin LQFP package, pins are grouped logically by functionality. Below are the critical pin categories required for motherboard troubleshooting. 1. Power and Ground Pins
Built-in matrix scanning engine supporting up to an 18x8 keyboard matrix.
Below is a breakdown of its core technological features:
: Features an internal 128KB programmable eFlash (Embedded Flash) memory for firmware storage. it8995e 128 datasheet
IT8995E-128/CX, IT8995E-128/CXA, and IT8995E-128/DXA.
The IT8995E-128 requires a 32.768 kHz real-time clock crystal for power management timers. Without it, S3/S5 wake-up events fail.
A detailed repair case on a motherboard presented the following scenario: Because the IT8995E-128 utilizes a 128-pin LQFP package,
Monitoring charge levels and managing charging circuits.
Ensure the WRST# pin is at 3.3V. If it is stuck at 0V, the chip will remain in a permanent reset state. High Current Draw / Heating Chip
The chip’s support for suggests that its internal USB-C PD controller can manage the high-speed data lanes of the Type-C connector, not just power delivery. Power and Ground Pins Built-in matrix scanning engine
💡 : Because this chip contains internal Flash memory, it may require programming with specific firmware (firmware version varies by laptop model) before it will function correctly on a new motherboard. If you'd like, I can help you find: Specific schematics for a laptop model using this chip.
128 KB of on-chip programmable flash memory (indicated by the "-128" suffix) used to store the EC firmware.
