M052LDN Datasheet, PDF (10/86 Pages) List of Unclassifed Manufacturers – 32-bit Microcontroller

M051 DN/DE
 I²C
 Up to two sets of I²C modules
 Supports Master/Slave mode
 Bidirectional data transfer between master and slave
 Multi-master bus (no central master)
 Arbitration between simultaneously transmitting masters without corruption of serial
data on the bus
 Serial clock synchronization allows devices with different bit rates to communicate via
one serial bus
 Serial clock synchronization can be used as a handshake mechanism to suspend and
resume serial transfer
 Programmable clocks allow versatile rate control
 Supports multiple address recognition (four slave addresses with mask option)
 ADC
 12-bit SAR ADC
 Up to 8-ch single-ended input or 4-ch differential input
 Supports Single mode/Burst mode/Single-cycle Scan mode/Continuous Scan mode
 Supports 2’ complement/un-signed format in differential mode conversion results
 Each channel with an individual result register
 Supports conversion value monitoring (or comparison) for threshold voltage detection
 Conversion started either by software trigger or external pin trigger
 A/D conversion started by PWM center-aligned trigger or edge-aligned trigger
 PWM trigger delay function
 Supports conversion result with signed format in Differential input and Burst mode
 Analog Comparator
 Up to four sets of Comparator analog modules
 External input or internal band-gap voltage selectable at negative node
 Interrupt when compared results change
 Power-down wake-up
 EBI (External Bus Interface) for external memory-mapped device access
 Accessible space: 64 KB in 8-bit mode or 128 KB in 16-bit mode
 Supports 8-bit or 16-bit data width
 Supports byte-write in 16-bit data width
 ISP (In-System Programming) and ICP (In-Circuit Programming)
 IAP (In-Application Programming)
 One built-in temperature sensor with 1℃ resolution
 BOD (Brown-out Detector)
 With 4 levels: 4.4V/3.7V/2.7V/2.2V
 Supports Brown-out interrupt and reset option
 96-bit unique ID
 LVR (Low Voltage Reset)
 Threshold voltage level: 2.0V
 Operating Temperature:
