NS9210B-0-I75

Application Specific Microcontrollers Overview

The NS9210B-0-I75 is a microprocessor from the Digi NS9210 family, featuring an ARM926EJ-S core operating at 75 MHz. It utilizes a 32-bit data bus and is housed in a 177-pin BGA package with a 0.8 mm pitch. The processor operates on a 1.8 V core voltage and supports 3.3 V I/O levels. Key integrated peripherals include a 10/100 Mbit Ethernet MAC, a NIST-compliant 256-bit hardware AES accelerator, two Flexible Interface Modules (FIMs), and multiple serial interfaces such as UART, SPI, and I2C. It includes 4 kB instruction cache and 4 kB data cache.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'I75' against official Digi documentation to confirm the exact speed grade and temperature range, as datasheets list 75/150 MHz variants. Confirm availability status, as older NS9210 models may be discontinued or subject to limited supply constraints. Ensure compatibility with existing NET+OS development environments if upgrading from previous designs.

Application Specific Microcontrollers Selection Notes

Select this model for applications requiring a cost-efficient, small-footprint ARM9 solution with integrated networking and security features. The 75 MHz speed grade is suitable for moderate processing loads. Consider the NS9215 variant if higher pin counts or additional peripherals are required. Verify that the 177-pin BGA package fits the target PCB layout and thermal requirements.

Application Specific Microcontrollers Part Context

The NS9210B-0-I75 belongs to the 32-bit NET+ARM Processor Family, designed as a successor to the NS7520 with pin compatibility. It is part of a broader ecosystem supported by the royalty-free NET+OS platform based on ThreadX RTOS. Development tools include the Digi ESP IDE and Green Hills MULTI options, facilitating rapid deployment of IPv4/IPv6 enabled embedded devices.
