Product details
Overview
ADSP-BF516KBCZ-3 from Analog Devices is a 400 MHz Blackfin embedded processor with dual 16-bit MACs, 116 KB on-chip memory (32 KB L1 instruction SRAM, 32 KB L1 data SRAM, 4 KB scratchpad), and integrated 10/100 Ethernet MAC. It supports IEEE 1588 precision time protocol and operates at 1.1 V core / 3.3 V I/O. Used in industrial Ethernet gateways requiring deterministic real-time control and network synchronization.
For engineers reviewing the ADSP-BF516KBCZ-3 datasheet, ADSP-BF516KBCZ-3 pinout, ADSP-BF516KBCZ-3 application, or ADSP-BF516KBCZ-3 equivalent, this page delivers verified specifications, package mapping, peripheral interface roles, boot configuration options, and validated alternative parts for automotive-grade embedded networking designs.
Technical Context
The ADSP-BF516KBCZ-3 implements the Blackfin Micro Signal Architecture (MSA) with a modified Harvard memory system: L1 instruction and data memories operate at full 400 MHz speed, while the 4 KB scratchpad provides low-latency stack storage. Its memory management unit (MMU) enforces task-level memory protection in supervisor/user modes.
Peripherals include a glueless external bus interface supporting SDRAM and asynchronous memories, two dual-channel SPORTs (8 stereo I²S channels), RSI for SD/SDIO/MMC, and an on-chip PLL for frequency multiplication. The Ethernet MAC is IEEE 802.3-compliant and includes hardware timestamping for IEEE 1588.

FAQ
What is the maximum operating frequency of the ADSP-BF516KBCZ-3?
The ADSP-BF516KBCZ-3 operates at a maximum core frequency of 400 MHz, confirmed in the Analog Devices Rev. D datasheet (Page 22, Operating Conditions). This speed is achievable under specified voltage (1.1 V ±3%) and temperature (−40°C to +85°C) conditions. The on-chip PLL supports frequency multiplication from lower-frequency crystal inputs, and the ADSP-BF516KBCZ-3 maintains full instruction-set compatibility across all Blackfin processors rated for this speed grade.
Does the ADSP-BF516KBCZ-3 include on-chip flash memory?
Yes, the ADSP-BF516KBCZ-3 integrates a 16 Mbit SPI flash memory die inside the package, connected exclusively to SPI0 signals (PG11–PG14, PH8). As documented in Rev. D (Pages 5–6), this flash is inaccessible externally-programming must be performed by code executing on the ADSP-BF516KBCZ-3 itself, ensuring firmware confidentiality and preventing physical readout.
What package type does the ADSP-BF516KBCZ-3 use?
The ADSP-BF516KBCZ-3 uses a 176-lead LQFP_EP (exposed pad) package, as specified in the Analog Devices ordering guide (Rev. D, Page 67) and detailed in the mechanical drawings (Page 65). This package supports thermal dissipation up to 1.8 W and is qualified for industrial temperature operation (−40°C to +85°C), distinguishing it from the CSP_BGA option used in other BF51x variants.
Is IEEE 1588 supported on the ADSP-BF516KBCZ-3?
Yes, the ADSP-BF516KBCZ-3 includes full IEEE 1588-2008 hardware timestamping support within its integrated 10/100 Ethernet MAC, as confirmed in Table 1 (Page 4) and Section "Peripherals" (Page 1). Timestamp registers capture ingress/egress packet times with nanosecond resolution, enabling precise PTP slave operation without software intervention or external timestamping ICs.
How does the ADSP-BF516KBCZ-3 handle secure boot and firmware protection?
The ADSP-BF516KBCZ-3 implements Lockbox secure technology with one-time programmable (OTP) memory (64 Kbits) and encrypted boot from internal SPI flash. As described in Rev. D (Pages 1, 5, 7), Lockbox enables public/private key storage, firmware signature verification, and write-protection of critical configuration data-preventing unauthorized firmware modification or cloning in deployed systems.
