General Description
Features
S ARM926EJ-S™ Processor Core with 16KB Data
DeepCover® embedded security solutions cloak sensi-
tive data under multiple layers of advanced physical
security to provide the most secure key storage possible.
Cache and 32KB Instruction Cache
S 384MHz Core Operating Frequency Via PLL
S 192MHz Multilayer AHB Bus Matrix
The DeepCover Secure Microcontroller (MAX32590)
provides an interoperable, secure, and cost-effective
solution to build new generations of trusted devices such
as multimedia-enabled portable EFT-POS terminals. The
MAX32590 integrates a memory management unit (MMU),
32KB of instruction cache, 16KB of data cache, 4KB
instruction TCM, 4KB data TCM, 384KB of system RAM, 2KB
of one-time-programmable (OTP) memory, 128KB of boot
ROM, and 24KB of battery-backed SRAM. The MAX32590
maximizes on-chip bandwidth when dealing with high-speed
communication such as 100Mbps Ethernet, large color LCD
displays, and gigabit-sized mass storage devices.
