Description
The electronic component model 83C154VF49 belongs to the product category of IC chips. It is a higher performance 8-bit microcontroller designed for the high-speed version of the existing MSM80C154/MSM83C154, providing low-power consumption. The MSM80C154S/MSM83C154S fully covers the functions and operating range of the existing MSM80C154/83C154/80C51F/80C31F. The MSM80C154S and the MSM83C154S are identical, except that the latter does not contain any internal program memory (ROM).
Specifications and features
- Operating Range:
- Operating Frequency: 0 to 3 MHz (Vcc=2.2 to 6.0 V), 0 to 12 MHz (Vcc=3.0 to 6.0 V), 0 to 24 MHz (Vcc=4.5 to 6.0 V)
- Operating Voltage: 2.2 to 6.0 V
- Operating Temperature: –40 to +85°C (Operation at +125°C conforms to the other specification.)
- Fully static circuit
- Upward compatible with the MSM80C51F/80C31F
- On-chip program memory: 16K words x 8 bits ROM (MSM83C154S only)
- On-chip data memory: 256 words x 8 bits RAM
- External program memory address space: 64K bytes ROM (Max)
- External data memory address space: 64K bytes RAM
- I/O ports: 4 ports x 8 bits (Port 1, 2, 3, impedance programmable): 32
- 16-bit timer/counters: 3
- Multifunctional serial port:
- I/O Expansion mode
- UART mode (featuring error detection)
- 6-source 2-priority level Interrupt and multi-level Interrupt available by programming IP and IE registers
- Memory-mapped special function registers
- Bit addressable data memory and SFRs
- Minimum instruction cycle: 500 ns @ 24 MHz operation
- Standby functions:
- Power-down mode (oscillator stop)
- Activated by software or hardware; providing ports with floating or active status
- The software power-down stet mode is terminated by interrupt signal enabling execution from the interrupted address.
Application Scenarios
The 83C154VF49 can be used in various electronics devices as a microcontroller, such as cameras, smartwatches, traffic lights, automobiles, and many others. It can be useful in situations where a low-power consumption and high-speed microcontroller is needed.
Comparison
Advantages- The MSM80C154S/MSM83C154S provides low-power consumption and supports a wide range of operating frequency, voltage, and temperature.
- It is upward compatible with the MSM80C51F/80C31F microcontrollers.
- It has a fully static circuit and provides various I/O ports and timer/counters.
- The MSM83C154S has on-chip program memory, which eliminates the need for external program memory.
- It has bit addressable data memory and SFRs, which makes it easier to handle individual bits of data.
Disadvantages- The MSM80C154S/MSM83C154S microcontrollers have a minimum instruction cycle of 500 ns, which may cause delays in certain applications that require faster processing time.
- The maximum size for external program and data memory address space is 64K bytes, which may not be large enough for certain applications.
