EtherCAT Slave Controller SoC

True Random Number Generator (TRNG)

2.4.1

Overview

The True Random Number Generator (TRNG) is used to generate the randomness by extracting from physical

phenomena.

2.4.2

Features

⚫

Generates 800 random bits per second

Flash Memory Controller (FMC)

2.5.1

Overview

The FMC is equipped with dual-bank on-chip embedded Flash (BANK0 and BANK1) for application and

configurable Data Flash to store some application dependent data. Both BANK0 and BANK1 have 64/128/256

Kbytes space. Thus, the total size of application rom (APROM) is 128K/256K/512K. A User Configuration

block provides for system initiation in BANK0. A 4 Kbytes loader ROM (LDROM) is used for In-System-

Programming (ISP) function in BANK0. A 4 Kbytes security protection ROM (SPROM) can conceal user

program. A 2 Kbytes one-time-program ROM (OTP) is used for recording one-time-program data in BANK1. A

32K Boot Loader consists of native ISP functions. A 4KB cache with zero wait cycle is used to improve Flash

access performance. This chip also supports In-Application-Programming (IAP) function. User switches the

code executing without chip reset after the embedded Flash is updated.
