For some vehicle systems or body electronic control systems, the current market share is mainly controlled by several foreign semiconductor manufacturers, such as NXP, Renesas, Infineon, Elmos, TI, ST and Microchip. Today, the editor mainly talks about NXP‘s car-grade MCU.

1. NXP‘s car gauge chip has S12 core Magniv series

For the S12 core, only the Magniv series is still in the main push state. The MagniV series chips are highly integrated and easy-to-use mixed-signal microcontrollers for automotive applications. It combines MCU, MOSFET gate driver, voltage regulator (12V-5V ) and the Local Interconnect Network (LIN) physical layer are four system elements combined into a single-chip solution.

For the upgrade iteration of S12 Magniv products, it is based on the ARM core S32M series. It can be seen that NXP unified the S32K platform in the upgrade plan, and then transitioned to the ARM core architecture. They all have richer system support and can be extremely useful in the software ecological chain. A large degree of reuse reduces the complexity of development.

2. NXP‘s car gauge chips include KEA series

The whole series is ARM M0+ core, so it can only be used in the control of some small nodes in the car, such as lights, seat control, etc.

3. NXP‘s car gauge chips include S32K1xx series

At present, this series has been mass-produced across the board. KEA products can be said to be a perfect low-end product, because KEA flash is from 8kb to 128kb, then S32K is from 128kb to the highest 2M flash, so it can cover absolutely everything in automotive electronics applications. A need for most. In fact, why is S32K called K? In fact, it is the abbreviation of KEA, which is equivalent to the iteration of the product.

Both KEA and S32K belong to the GPIS department of NXP, and GP is also the General purpose, so they are all general-purpose vehicle gauge controllers.

4. NXP‘s car gauge chips include S32K3xx series

For high-end applications, NXP is planning the S32K3xx series. Compared with the K1, the performance of the K3 has been improved in almost all directions, in the main frequency, Memory, Security, Safety, peripherals, etc.

5. NXP‘s automotive-grade chips have Power PC architecture series

This is the joint development of NXP and ST. I roughly understand that the achievement is the same product. Then the price of ST is generally more advantageous than that of NXP, so I just don’t play it. The market share of this series is very small. After the S32K3xx comes out, In terms of resources and performance, it can well cover the application scenarios of the Power PC architecture, which is likely to weaken the promotion of SPC56 and 57.

NXP automotive-grade chips also include S32G, S32R, and i.MX6 and i.MX8 series, which are mainly used in specific applications or scenarios that require image processing. If you want to know more about the details of NXP automotive-grade chips, please consult Hao Qi Core Technology.
