3.4.4
Memory
3.4.4.1
DDR3L SDRAM
The TQMx50UC supports a memory-down dual-channel DDR3L configuration without error-correcting code (ECC), running at
up to 1600 MT/s. The maximum memory size is 8 Gbyte. The available memory configuration can be either 4 Gbyte or 8 Gbyte.
3.4.4.2
SPI Boot Flash
The TQMx50UC provides a 128 Mbit SPI boot flash. It includes the Intel
®
Management Engine (Intel
®
ME) and the uEFI BIOS. An
external SPI boot flash can be used instead of the on-board SPI boot flash. The uEFI BIOS supports the following 3.3 V SPI flash
devices on the carrier board:
•
Winbond W25Q128FV
•
Macronix MX25L12835F
3.4.4.3
EEPROM
The TQMx50UC provides an EEPROM. The 32 kbit (24AA32) EEPROM is connected to the general purpose I2C interface
(COM Express™ pins I2C_DAT and I2C_CK).
3.4.5
Real Time Clock
The TQMx50UC provides a standard RTC (Motorola MC146818B) integrated in the 5
th
Generation Intel
®
Core™ 5000U processor
series and a high accuracy, ultra-low-power industrial RTC (iRTC) as an assembly option.
The following list illustrates some key features of the iRTC:
•
Lowest current consumption (typ. 240 nA)
•
Optimized for GoldCap
®
capacitor backup
•
Temperature compensation: –40 °C to +85 °C
•
Time deviation ±0.26 s/day / ±3.0 ppm
•
Time keeping voltage down to 1.5 V
Please contact
TQ-Support
for further information about the iRTC.
3.4.6
Trusted Platform Module
The TQMx50UC has been designed to support the Trusted Platform Module (TPM) 1.2 (Infineon SLB9660).
The TPM 2.0 configuration is available on request.
3.4.7
Hardware Monitor
The TQMx50UC provides an integrated Hardware Monitor to monitor the on-board and processor die temperature, board
voltages and manage the fan control of the COM Express™ interface (FAN_PWMOUT and FAN_TACHOIN).
3.4.8
TQ Flexible I/O Configuration (TQ-flexiCFG)
The TQMx50UC provides a flexible I/O configuration feature, TQ-flexiCFG.
Using the TQ-flexiCFG, several COM Express™ I/O interfaces and functions can be configured via a programmable FPGA.
This feature enables the user to integrate special embedded features and configuration options in the TQMx50UC to reduce
the carrier board design effort.
Here are some examples of the flexible I/O configuration:
•
GPIO interrupt configuration
•
Interrupt configuration via LPC Serial IRQ
•
Serial port handshake signals via GPIOs
•
Integrate additional I/O functions, e.g. additional Serial, CAN, I2C, PWM controller or special power management
configurations
