Added WLCSP64 package.

Section 3.1: Low power modes: changed ‘128 kHz’ to ‘131 kHz’ in

section “Low power run mode”.

Section 3.17.1: General-purpose timers (TIM2, TIM3, TIM4, TIM5,

TIM9, TIM10 and TIM11): changed ‘six’ to ‘seven’ synchronizable

general-purpose timers.

Table 9: STM32L15xxD pin definitions on page 37: updated name of

reference manual in footnote 5.

I2C updated: footnote 3. from Table 55

Note about I2C clock updated: footnote 2. from Table 55 modified.

Note [non-robust] updated: footnote 2. from Table 65 modified.

GPIOs high current capability updated: Section 3.6: GPIOs (general-

purpose inputs/outputs) ‘except for analog inputs’ was removed.

15-Jun-2012

Changed maximum number of touch sensing channels to 34, and

updated Table 2: Ultra-low-power STM32L15xxD device features and

peripheral counts.

Updated Section 3.11: ADC (analog-to-digital converter) to add

Section 3.11.1: Temperature sensor and Section 3.11.2: Internal

voltage reference (VREFINT).

Removed caution note below Figure 11: Power supply scheme.

Added note below Table 4: STM32L15xQD UFBGA132 ballout.

Modified Table 7: STM32L15xRD WLCSP64 ballout to match top

view.

Changed FSMC_LBAR into FSMC_NADV, and I2C1_SMBAI into

I2C1_SMBA in Table 9: STM32L15xxD pin definitions.

Modified PB10/11/12 for AFIO4 alternate function, and replaced

LBAR by NADV for AFIO12 in Table 10: Alternate function

input/output.

Updated Table 22: Typical and maximum current consumptions in

Stop mode and added Note 6. Updated Table 23: Typical and

maximum current consumptions in Standby mode. Updated tWUSTOP

in Table 24: Typical and maximum timings in Low power modes.

Updated Table 25: Peripheral current consumption.

Updated Table 57: SPI characteristics, added Note 1 and Note 3, and

applied Note 2 to tr(SCK), tf(SCK), tw(SCKH), tw(SCKL), tsu(MI), tsu(SI),

th(MI), and th(SI).

Updated IDD maximum value in Table 35: Flash memory and data

EEPROM characteristics.

Table 80.
