microcontroller price

We are using PIC18LF252 and It is $2.24 for 30K quantity per month.
I think that Microchip' s microcontrollers are expensive than others. What do you think about this ?

If you specify here which are your requests in terms of speed, peripherals, memory, ...., somebody might help you find less expensive products.

Speed is not too important for me. 1 MIPS is enough. Peripherals that I use are RTC, EEPROM (2048 byte), 2 UART, 1 SPI, 1 I2C and 96 segment LCD Driver. But I exactly wonder that usual situation which company sells their microcontroller the cheapest.

Oh, is not easy to find low cost MCU with all these requirements, expecially for 2kbyte eeprom and 2 UART.
Holtek 48R50 (3x33 or 4x32 LCD segments) +external 24C16 can be used, but only with up to 9600bps UARTs (they should be implemented in software: it has not UART peripheral inside) and about 50kbps SPI (connecting CLK to an interrupt pin).

I think that HT48R50 costs less than one dollar (may be 80-90 cents?? You must ask to a distributor, I don't know exactly), for 300k/year, but consider that softrware uart will limit the maximum bitrate on those ports.

I Agree HT48R50 or holtek family is really cheappp ... but 8051 is really cheap too.
