This means the manufacturer has ceased production and there is no official last-time-buy window remaining. Quantities are lot-specific and confirmed at RFQ — no stock-holding claim is made here. ## 80MHz Cortex-M3 with 512KB Flash The ARM Cortex-M3 core runs at 80 MHz, placing it in the mid-range of the Stellaris 1000 series. This clock speed handles real-time control loops and communication protocol stacks without external memory wait-states for most code. On-chip memory includes 512 KB of Flash and 64 KB of SRAM. The Flash is sufficient for a moderate application image plus a bootloader; the SRAM leaves room for a TCP/IP stack or a modest data buffer alongside the stack. ## 108-BGA package and rework considerations The 60 general-purpose I/O are distributed across the BGA periphery. Connectivity options include I²C, SPI, SSI, UART/USART, IrDA, LINbus, and Microwire — covering sensor buses, serial displays, and industrial fieldbus adapters. The 16-channel 12-bit ADC samples analog inputs without an external converter. On-chip peripherals include DMA, PWM, watchdog timer, and brown-out detect/reset — enough for a standalone motor-control or data-logging application without external supervisory ICs.","metaTitle":"TI LM3S1C58-IBZ80-A1 ARM Cortex-M3 MCU, 80MHz, 512KB Flash","metaDescription":"Texas Instruments LM3S1C58-IBZ80-A1 Stellaris ARM Cortex-M3 MCU, 80MHz, 512KB Flash, 64K RAM, 108-BGA.
