• 520 kB (8 kB RTC FAST Memory included) of on-chip SRAM for data and instruction.
– 8 kB of SRAM in RTC, which is called RTC FAST Memory and can be used for data storage; it is
accessed by the main CPU during RTC Boot from the Deep-sleep mode.
• 8 kB of SRAM in RTC, which is called RTC SLOW Memory and can be accessed by the co-processor
during the Deep-sleep mode.
• 1 kbit of eFuse, of which 320 bits are used for the system (MAC address and chip configuration) and
the remaining 704 bits are reserved for customer applications, including Flash-Encryption and Chip-ID.
4.2 External Flash and SRAM
KK-4000 supports up to four 16-MB of external QSPI flash and SRAM with hardware encryption based
on AES to protect developers’ programs and data.
KK-4000 can access the external QSPI flash and SRAM through high-speed caches.
• Up to 16 MB of external flash are memory-mapped onto the CPU code space, supporting 8, 16 and 32-
bit access. Code execution is supported.
• Up to 8 MB of external flash/SRAM are memory-mapped onto the CPU data space, supporting 8, 16 and 32-
KK-4000bit access. Data-read is supported on the flash and SRAM. Data-write is supported on the SRAM.
integrates 4 MB of external SPI flash. The 4-MB SPI flash can be memory-mapped onto the CPU code
space, supporting 8, 16 and 32-bit access. Code execution is supported.
4.3 Crystal Oscillators
The KK-4000 Wi-Fi/BT firmware can only support 40 MHz crystal oscillator for now.
