2.1.2
Memory
The AM4100 supports a single-channel (72-bit), registered Double Data Rate (DDR2) memory
with Error Checking and Correcting (ECC) running up to 600 MHz (PC3200). The available
memory configuration can be either 512 MB, 1 GB or 2 GB. ECC is able to correct single-bit
errors and detect multiple-bit errors.
2.2
Peripherals
The following standard peripherals are available on the AM4100 board:
2.2.1
Timer
The AM4100 is equipped with the following timers:
•
Real-Time Clock (RTC)
The AM4100 is equipped with an onboard high-precision real-time clock RV-8564-C2.
The RV-8564-C2 RTC is register-compatible with the PCF8564A RTC from Philips/NXP.
Additionally, it provides a very tight frequency tolerance at low power consumption.
The AM4100 does not include a 3 V lithium battery or a GoldCap power source for RTC
backup. The RTC can be powered from the management power. However, if this power
is switched off, the RTC will lose its data.
•
Hardware delay timer for short reliable delay times
