7.3 Main memory

A memory module is optional.

Tsi108 memory controller should be set to specifications of an intended module.

7.4 Backup SRAM

The A3pci7512 is equipped with a register-integrated backup SRAM (STMicro: M48T37V-10MH1E) and bat-

tery (STMicro: M4T32-BR12SH), which allows the use of the RTC according to the settings of this register. The

battery assures 5-year retention of SRAM data and time data with the power off (at 25 °C).

Refer to respective data sheets for details on the SRAM and battery.

7.5 CPU status LED

The CPU status LED, attached to the SIO1 connector on the panel, is configured to be controlled with Tsi108

GPIO pin.

LED and GPIO pin connections is as shown in table 7.3.

Each GPIO pin is capable to set for either input or output pin and also it can be set to output Hi/Lo in case of

output. Please set in accordance with the table 7.3 in using the pin.

[Table 7.3] CPU status LED and GPIO pin connections

7.6 General LED

The LED attached to the SIO2 connector of the panel side is controlled with usable LED voluntarily by a GPIO

pin of Tsi108.

LED and GPIO pin connections is as shown in table 7.4.

Each GPIO pin is capable to set for either input or output pin and also it can be set to output Hi/Lo in case of

output. Please set in accordance with the table 7.4 in using the pin.

[Table 7.4] General LED and GPIO pin connections
