FAQ
What is the maximum operating frequency of the LM3S600-EGZ50-C2T?
The LM3S600-EGZ50-C2T operates at a maximum system clock frequency of 50 MHz. This is achieved using an internal PLL that multiplies the input crystal or external clock source. The 50 MHz specification is validated across the commercial temperature range (0°C to 70°C) and under recommended supply conditions (3.3 V ±5%). Performance remains stable without throttling, making LM3S600-EGZ50-C2T suitable for deterministic real-time tasks such as motor phase timing and encoder counting.
Does the LM3S600-EGZ50-C2T support in-system programming via UART?
Yes, the LM3S600-EGZ50-C2T supports in-system programming through its built-in Serial Flash Loader (SFL), which operates over UART0 or SSI0. The SFL protocol allows firmware updates without JTAG hardware, using simple packet-based commands like COMMAND_DOWNLOAD and COMMAND_RUN. This capability is documented in Appendix A of the SPMS099I datasheet and enables field upgrades for deployed LM3S600-EGZ50-C2T units with minimal host-side software requirements.
What debug interface does the LM3S600-EGZ50-C2T provide?
The LM3S600-EGZ50-C2T provides ARM Serial Wire Debug (SWD) via SWCLK and SWDIO pins, offering full debug visibility-including breakpoints, watchpoints, register inspection, and memory access-with only two signal lines. It also supports legacy JTAG for compatibility with existing tools. Both interfaces are active simultaneously and do not require configuration; SWD is preferred for reduced pin count and faster debug session initialization during LM3S600-EGZ50-C2T development.
Is the LM3S600-EGZ50-C2T pin-compatible with any newer TI microcontrollers?
Yes, the LM3S600-EGZ50-C2T in 100-pin LQFP is pin-compatible with the TM4C123GH6PM, a member of TI's successor Tiva C Series. This compatibility extends to power, ground, GPIO, UART, I²C, SSI, and timer signal mappings. While peripheral registers differ, the shared pinout allows direct PCB reuse-making LM3S600-EGZ50-C2T a viable starting point for designs later upgraded to TM4C123GH6PM for enhanced performance and extended temperature support.
What are the supported low-power modes of the LM3S600-EGZ50-C2T?
The LM3S600-EGZ50-C2T supports Sleep, Deep-Sleep, and Hibernate modes. In Sleep mode, the CPU stops while peripherals remain active; Deep-Sleep disables the main oscillator and reduces current to ~150 µA; Hibernate mode retains RTC and wake-up logic using only the 32.768 kHz crystal and draws ~1.7 µA. All modes are entered via NVIC-defined sleep-on-exit or WFI/WFE instructions, and wake-up sources include GPIO interrupts, timer matches, and comparator events-enabling robust low-power operation in battery-powered LM3S600-EGZ50-C2T deployments.
