Description

The 32L152CDISCOVERY Discovery kit helps the development of applications

based on the STM32L1 Series microcontrollers and benefit from the ultra-low-power

features of these devices.

Based on the STM32L152RC microcontroller, this Discovery kit includes an ST-

LINK/V2 embedded debugging tool interface, a 24‑segment 4‑common LCD, LEDs,

push-buttons, a linear touch sensor, and touchkeys.

1 Ordering information

To order the 32L152CDISCOVERY ultra‑low‑power Discovery kit, refer to Table 1. For a detailed description

of each board, refer to its user manual on the product web page. Additional information is available from the

datasheet and reference manual of the target STM32.

1. The former STM32L-DISCOVERY Discovery kit offered the same features except for the STM32L152RB microcontroller

with 128 Kbytes of flash memory, 16 Kbytes of RAM, and 4 Kbytes of data EEPROM.

1.1 Product marking

The stickers located on the top or bottom side of all PCBs provide product information:

• First sticker: product order code and product identification, generally placed on the main board featuring

the target device.

Example:

Product order code

Product identification

• Second sticker: board reference with revision and serial number, available on each PCB.

Example:

MBxxxx-Variant-yzz

syywwxxxxx

On the first sticker, the first line provides the product order code, and the second line the product identification.

On the second sticker, the first line has the following format: “MBxxxx-Variant-yzz”, where “MBxxxx” is the board

reference, “Variant” (optional) identifies the mounting variant when several exist, “y” is the PCB revision, and “zz”

is the assembly revision, for example B01. The second line shows the board serial number used for traceability.

Parts marked as “ES” or “E” are not yet qualified and therefore not approved for use in production. ST is not

responsible for any consequences resulting from such use. In no event will ST be liable for the customer using

any of these engineering samples in production. ST’s Quality department must be contacted prior to any decision

to use these engineering samples to run a qualification activity.

“ES” or “E” marking examples of location:

• On the targeted STM32 that is soldered on the board (for an illustration of STM32 marking, refer to the

STM32 datasheet Package information paragraph at the www.st.com website).

• Next to the evaluation tool ordering part number that is stuck, or silk-screen printed on the board.

Some boards feature a specific STM32 device version, which allows the operation of any bundled commercial

stack/library available. This STM32 device shows a “U” marking option at the end of the standard part number

and is not available for sales.

To use the same commercial stack in their applications, the developers might need to purchase a part number

specific to this stack/library. The price of those part numbers includes the stack/library royalties.
