NXP Semiconductors K32L2B11VMP0AR

Overview

K32L2B11VMP0AR from NXP Semiconductors is a 48 MHz Arm® Cortex®-M0+ microcontroller with 64 KB flash, 32 KB SRAM, and 16 KB ROM bootloader, designed for ultra-low-power battery-operated devices requiring USB FS connectivity and segment LCD support. It delivers 54 µA/MHz in very low power run mode, 1.96 µA in deep sleep (RAM + RTC retained), and integrates USB 2.0 device controller with crystal-less operation, SLCD up to 24×8 segments, and FlexIO for serial peripheral emulation.

For engineers reviewing the K32L2B11VMP0AR datasheet, K32L2B11VMP0AR pinout, K32L2B11VMP0AR application, or K32L2B11VMP0AR equivalent, key selection criteria include its 64-pin MAPBGA package, 1.71–3.6 V operating voltage, –40 to 105 °C temperature range, integrated 16-bit ADC (461 ksps, 16-channel), and hardware security features including 80-bit UID and flash protection.

Technical Context

The K32L2B11VMP0AR implements an Arm Cortex-M0+ core with VTOR-based vector table relocation and supports boot from internal flash or embedded ROM bootloader. Its clock system combines HIRC48M (±0.5%), LIRC8M/2M (±3%), and 32–40 kHz/3–32 MHz crystal oscillators, enabling USB FS timing compliance without external crystal.

Power management includes six static modes (Run/VLPR, Wait/VLPW, Stop/VLPS, LLS, VLLS0–3), with LLWU and AWIC controllers managing wake-up from deep sleep states using GPIO, RTC, LPTMR, or CMP sources. Peripherals are clock-gated per module, with bus, platform, and system clocks independently configurable per Table 4 of the datasheet.

FAQ

What is the maximum operating frequency of the K32L2B11VMP0AR?

The K32L2B11VMP0AR features an Arm Cortex-M0+ core rated for up to 48 MHz operation. This frequency is sustained using the internal HIRC48M oscillator, which maintains ±0.5% accuracy across temperature and voltage - enabling deterministic real-time performance without external clock components. The K32L2B11VMP0AR achieves this speed while consuming only 54 µA/MHz in very low power run mode.

Does the K32L2B11VMP0AR support crystal-less USB Full-Speed operation?

Yes, the K32L2B11VMP0AR integrates a trimmed HIRC48M oscillator that meets USB 2.0 Full-Speed timing requirements (±0.25% tolerance) without requiring an external 12 MHz crystal. This capability is confirmed in Section 2.1.6 and Table 4 of the official NXP datasheet Rev. 3 (09/2020), reducing BOM cost and PCB area. The K32L2B11VMP0AR USB controller operates exclusively in device mode.

What package type and dimensions does the K32L2B11VMP0AR use?

The K32L2B11VMP0AR is supplied in a 64-pin MAPBGA package measuring 5 mm × 5 mm with 0.5 mm pitch and 1.23 mm thickness (package drawing 98ASA00420D). This compact, thermally efficient package supports automated assembly and provides excellent signal integrity for high-speed peripherals like USB and SPI. Pin assignments match those documented in Section 4.5 of the K32L2B3x datasheet.

How much SRAM and flash memory does the K32L2B11VMP0AR include?

The K32L2B11VMP0AR integrates 32 KB of on-chip SRAM accessible at CPU clock speed with zero wait states, and 64 KB of program flash memory organized in 1 KB pages. It also includes 16 KB of ROM containing a production-grade bootloader supporting UART, I²C, SPI, and USB firmware updates - all verified in Section 2.1.4 and Table 1 of the NXP datasheet.

What is the lowest power consumption mode supported by the K32L2B11VMP0AR?

The K32L2B11VMP0AR achieves 1.96 µA in VLLS3 mode, retaining full 32 KB SRAM contents and RTC operation while disabling the core and most peripherals. This mode is validated in Section 2.1.8 and Table 6 of the datasheet, and is enabled via the Power Management Controller (PMC) with LLWU wake-up sources active. The K32L2B11VMP0AR supports six distinct low-power states to match application-specific energy budgets.
