'''Au1500-333MBD''' was a {{arch|32}} ultra low power embedded microprocessor with an {{alchemy|Au1|l=arch}} CPU core implementing the [[MIPS32]] ISA. Designed by [[Alchemy Semiconductor]] and fabricated on a [[TSMC]] [[180&nbsp;nm]] LV process, this {{abbr|SoC}} operates at a base frequency of up to 333 MHz with a typical {{abbr|TDP}} of 400 mW. It was also available with an industrial temperature range as {{\\|Au1500-333MBF}} and is the Pb-free version of the {{\\|Au1500-333MBC}}.

== Memory controller ==
Au1500 processors integrate two independent memory controllers, a DRAM controller which supports SDRAM, {{abbr|SMROM}}, and SyncFlash, and a static bus controller which supports SRAM, ROM, Flash memory, {{abbr|PCMCIA}}/CompactFlash devices, and I/O peripherals such as an external LCD controller. SDRAM runs at one half of the frequency of the internal 32-bit System Bus, which runs at up to one half of the CPU core frequency.
