ST’s STM32F373/383 devices deliver a different blend of peripheral functions. They integrate a 16-bit sigma-delta ADC on-chip, allowing the STM32 family to solve a wider range of precision-sensing applications and so provide a single-chip solution capable of replacing a discrete general-purpose processor and separate ADC. Up to three 16-bit sigma-delta ADCs are integrated on-chip, with separate analog supply from 2.2 to 3.6 V, up to 21 single or 11 differential channels, and seven programmable gains per channel.

Other STM32F373/383 analog peripherals include two fast comparators, three 12-bit DACs, and one 12-bit 1 MSPS ADC. There is also an enhanced CEC (consumer electronics control) unit, making these devices ideal for consumer multimedia products. Compared to the STM32 F1 series, STM32F373/383 devices provide a system-on-chip solution enabling developers to reduce the bill of materials and simplify board designs.

The STM32F373/383 devices includes 2 variants:

• STM32F373 with larger peripheral set, operating from 2.0 to 3.6 V
• STM32F383 identical to the STM32F373, operating at 1.8 V +/-8%
