peripherals and may individually shut down and gate the clocks of any or all peripherals for power savings.
The on-chip debugging interface (SWJ-DP) allows non-intrusive (uses no on-chip resources), full speed, in-circuit
debugging using the production MCU installed in the final application. This debug logic supports inspection and
modification of memory and registers, setting breakpoints, single stepping, and run and halt commands. All analog
and digital peripherals are fully functional while debugging.
Each device is specified for 1.8 to 3.8 V operation over the industrial temperature range (–40 to +85 °C). The
SiM3L1xx devices are available in 40-pin or 64-pin QFN, 64-pin or 80-pin TQFP, and 80-pin TFBGA packages. All
package options are lead-free and RoHS compliant. See Table 5.1 for ordering information. A block diagram is
included in Figure 4.1.
