Analog Devices ADSP-BF52x Blackfin Processor Hardware Reference Manual
This document serves as a hardware reference guide for the ADSP-BF52x Blackfin processor family. It provides detailed specifications on the chip bus hierarchy, including Core Bus, Peripheral Access Bus (PAB), DMA buses, and External Access Bus (EAB). The manual details the memory architecture, encompassing internal SRAMs, caches, Boot ROM, and OTP memory programming.
The guide extensively covers peripheral interfaces such as Ethernet MAC, SPI, I2C/TWI, UART, Timers, and various DMA modes. It also includes sections on system interrupts, dynamic power management states (Full-On, Active, Sleep, Deep Sleep), voltage regulation, and specific timing specifications for SDRAM controllers.

Questions answered in these manuals
What processor models does this application note cover?
This document discusses the NAND flash controller on ADSP-BF52x and ADSP-BF54x Blackfin processors.
From: Analog Devices Using the NAND Flash Controller on Blackfin Processors EE-344
What is the maximum number of program/erase cycles for NAND flash blocks?
The number of program/erase cycles will vary from 10,000 to 100,000 times before a block is no longer reliable.
From: Analog Devices Using the NAND Flash Controller on Blackfin Processors EE-344
What are the timing specifications for standard and fast mode Two-Wire Interface transfers?
Standard mode supports up to 100K bits/s, while fast mode supports up to 400K bits/s.
From: Analog Devices ADSP-BF52x Blackfin Processor Hardware Reference Manual
What is the recommended procedure for changing the SDRAM powerup sequence during runtime?
The system must issue an SSYNC instruction, set the SDRAM to self-refresh mode by writing a 1 to the SRFS bit of EBIU_SDGCTL, execute the PLL programming sequence, reprogram the SDRAM registers with values appropriate for the new frequency, and then clear the SRFS bit.
