Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM3S9B92-IQC50-A2 | Same Cortex-M3 core, 512 KB flash, 96 KB SRAM, identical pinout and peripheral set | Higher memory capacity supports larger protocol stacks (e.g., full TCP/IP + TLS) and firmware-over-the-air updates | Select when application requires >256 KB code space or extended data logging buffer |
| TM4C123GH6PM | Successor series with same footprint, 256 KB flash, 32 KB SRAM, added USB OTG and enhanced analog peripherals | Lacks integrated Ethernet MAC; requires external PHY; optimized for USB-hosted human interface rather than wired industrial networking | Select for new designs prioritizing long-term availability and USB connectivity over legacy Ethernet/CAN integration |
Compared with LM3S9B92-IQC50-A2, the LM3S8530-IQC50-A2 offers lower memory cost for fixed-function applications; versus TM4C123GH6PM, it retains native Ethernet MAC but lacks USB and has reached end-of-life-making it suitable only for legacy design refresh or cost-sensitive volume production where TI's discontinuation timeline is managed.

FAQ
What is the maximum operating frequency of the LM3S8530-IQC50-A2?
The LM3S8530-IQC50-A2 operates at a maximum CPU frequency of 50 MHz, as specified in the production data sheet. This clock speed is achieved using the internal PLL with an external crystal or oscillator input. The LM3S8530-IQC50-A2 maintains full peripheral functionality-including CAN, Ethernet, and PWM-at this rated frequency under industrial temperature conditions.
Does the LM3S8530-IQC50-A2 include an integrated Ethernet PHY?
No, the LM3S8530-IQC50-A2 integrates only the Ethernet MAC layer and requires an external PHY chip connected via the MII interface. The LM3S8530-IQC50-A2 provides all necessary MAC registers, DMA control, and frame filtering logic, but physical layer signaling (10BASE-T/100BASE-TX) must be handled by a discrete PHY such as the DP83848 or LAN8720.
Is the LM3S8530-IQC50-A2 pin-compatible with other Stellaris LM3S devices?
The LM3S8530-IQC50-A2 uses a 100-pin LQFP package shared with several LM3S variants including LM3S8962 and LM3S9B92, but pin assignments for peripheral functions differ across models. While package footprint is identical, signal mapping on PA–PG ports varies; therefore, direct PCB replacement without schematic and layout review is not supported for the LM3S8530-IQC50-A2.
What development tools support the LM3S8530-IQC50-A2?
The LM3S8530-IQC50-A2 is supported by Texas Instruments' Code Composer Studio v5.x and earlier, Keil MDK-ARM v4.x, and IAR Embedded Workbench for ARM. TI's Stellaris Peripheral Driver Library and evaluation boards like the EK-LM3S8962 provide validated startup code, peripheral examples, and JTAG debugging for the LM3S8530-IQC50-A2.
What is the status of the LM3S8530-IQC50-A2 in Texas Instruments' product lifecycle?
The LM3S8530-IQC50-A2 is listed as Not Recommended for New Designs (NRND) and has entered the Product Discontinuance Notice phase per TI's official product change notices. Aetrix Electronics maintains limited inventory and offers last-time-buy support, with full traceability and documentation for legacy program continuity of the LM3S8530-IQC50-A2.
