Newest member of the STM32 family with CAN are the Cortex M0 types STM32F04x and STM32F07x. Working @48 MHz and up to 128KiB Flash they offer one CAN channel and USB
As with other STM32 devices, the ST bxCAN module is implemented.
F0x1 has CAN, F0x2 has CAN and USB. STM32F072B_DISCOVERY available. more details here without CAN transceiver.. Or the STM32072B-EVAL with DSUB9 CAN connector but more expensive.
Outstandingly Ultra-Low-Power MCUs, CAN not implemented (yet?)
The STM32 family of 32‑bit Flash microcontrollers based on the ARM Cortex™‑M processor is designed to offer new degrees of freedom to MCU users. It offers 32‑bit product range that combines high performance, real‑time capabilities, digital signal processing, and low‑power, low‑voltage operation, while maintaining full integration and ease of development. The unparalleled and large range of STM32 devices, based on an industry-standard core and accompanied by a vast choice of tools and software, makes this family of products the ideal choice, both for small projects and for entire platform decisions.

All STM32 families are implementing CAN using the ST bxCAN module. But not all family members have CAN. Most have.
SPC58 family of multi-core micro-controllers, enable functional safety and encryption in automotive systems (ASIL-B), for applications like advanced driver assistance systems (ADAS). Up to 6 MiB Flash and 768 KiB internal RAM memory, eight CAN interfaces, seven Bosch M_CAN, all ISO CAN-FD compliant, and 1 Time-Triggered Controller Area Network M_TTCAN.
SPC58NE84E7, SPC58NE84C3 Data sheet (PDF)
SPC57 family integrates the Bosch M_CAN module . First samples do support only 8 byte in the data frame, final versions will support 64 byte data frames by end of 2013. Update 3/2015: no news regarding CAN FD. The data sheet does not mention CAN FD.
The SPC56 family 32-bit MCUs for Automotive are designed using Power Architecture™ and ST’s embedded Flash technology. Developed within the framework of the STMicroelectronics/Freescale Joint Development Program (JDP), it combines a scalable range of e200 cores with innovative peripheral sets that are optimized for building efficient applications in engine management, chassis, safety, body control and instrument clusters. They contain up to 6 FlexCAN with 64-message objects each.

SPEAr (Structured Processor Enhanced Architecture) controllers are based on 32-bit ARM® ARM926EJ-S or Cortex™-A9 cores
- SPEAr 320 - ARM926 based, 2 CAN Channels based on BOSCH C_CAN
- SPEAr 1310 - dual Cortex-A9 based, 2 CAN Channels
- STA1085 / STA1095 Accordo2 Dual Core 32-bit ARM Cortex-R4 / Cortex-M3 processor, with embedded SRAM, integrated DSP sound subsystem, audio ADCs and DACs, isolated CAN, MCU for Car Radio and Display Audio applications. ARM Cortex-M3 controller is dedicated for real-time CAN / Vehicle Interface Processing. Embedded secure CAN subsystem:
- Dedicated ARM Cortex-M3 core
- Isolated embedded memory
- CAN ports
- Secured NOR interface
STA1085 and STA1095 allows isolating critical code from main application by implementing a dedicated subsystem based on ARM Cortex-M3, along with:
- 256KB dedicated embedded SRAM
- CAN controller
- Dedicated GPIOs
In order to guarantee security of CAN network, it can be completely isolated from the rest of the system, in such a way that no application running on Cortex-R4 can access by any mean to CAN specific resources. The secure sub-system communicates with the application running on Cortex-R4 using a Hardware Mailbox interrupt based mechanism.
