ATSAM3N4A

The ATSAM3N4A is designed as one kind of low-power audio DSP /  low-cost effects DSP device that includes three 24-bit DSPs, a 24-bit Audio Router and a general purpose 16-bit on-chip CISC Microcontroller. And this device can be controlled by an external host processor through the unidirectional serial interface.

Features of the ATSAM3N4A are:(1)Three DSPs and 24-bit Audio Router On-chip; (2)32 kHz to 96 kHz Sampling Rate; (3)16-bit Microcontroller On-chip; (4)Variety of I/Os, including SmartMedia and DataFlash Embedded RAM for Single Chip Operation (530 kbit); (5)Warm Start Power-down; (6)1 uA Typical Deep Power-down, 0.5 mW/MIPS Typical Operating; (7)External Flash/ROM Capability; (8)Available in a 64-lead TQFP Package.

The absolute maximum ratings of the ATSAM3N4A can be summarized as:(1)Ambient Temperature (power applied): -40°C to 85°C;(2)Storage Temperature: -65°C to 150°C;(3)Voltage on any pin X1, LFT: -0.3 to VC18+0.3V;(4)Voltage on any pin Others: -0.3 to VC33+0.3V;(5)Maximum IOL per I/O pin: 4 mA.
