For those who like the Attiny85 but need some more grunt, how about the new LPC800, 32-bits in a DIP8 package (and others)
Surely this has to be a hobbyist's dream.
The only down side (and it can be a biggy in some applications) is no ADC, but there is this, 3 USARTs, 2 SPI, and an I2C interface with USART and I2C driver in ROM so they don't use any flash memory. 30Mhz with no crystal, CRC engine, boot loader in ROM, 16k flash and 4k RAM, full debugging support, yada yada yada.
I think I'm in love.
System: * ARM Cortex-M0+ processor, running at frequencies of up to 30 MHz with single-cycle multiplier and fast single-cycle I/O port. * ARM Cortex-M0+ built-in Nested Vectored Interrupt Controller (NVIC). * System tick timer. * Serial Wire Debug (SWD) and JTAG boundary scan modes supported. * Micro Trace Buffer (MTB) supported. Memory: * Up to 16 kB on-chip flash programming memory with 64 Byte page write and erase. * 4 kB SRAM. * ROM API support: * Boot loader. * USART drivers. * I2C drivers. * Power profiles. * Flash In-Application Programming (IAP) and In-System Programming (ISP). Digital peripherals: * High-speed GPIO interface connected to the ARM Cortex-M0+ IO bus with up to 18 General-Purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors. * GPIO interrupt generation capability with boolean pattern-matching feature on eight GPIO inputs. * Switch matrix for flexible configuration of each I/O pin function. * State Configurable Timer (SCT) with input and output functions (including captureand match) assigned to pins through the switch matrix. * Multiple-channel multi-rate timer (MRT) for repetitive interrupt generation at up to four programmable, fixed rates. * Self Wake-up Timer (WKT) clocked from either the IRC or a low-power, low-frequency internal oscillator. * CRC engine. * Windowed Watchdog timer (WWDT). Analog peripherals: * Comparator with external voltage reference with pin functions assigned or enabled through the switch matrix. Serial interfaces: * Three USART interfaces with pin functions assigned through the switch matrix. * Two SPI controllers with pin functions assigned through the switch matrix. * One I2C-bus interface with pin functions assigned through the switch matrix. Clock generation: * 12 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used as a system clock. * Crystal oscillator with an operating range of 1 MHz to 25 MHz. * Programmable watchdog oscillator with a frequency range of 9.4 kHz to 2.3 MHz. * 10 kHz low-power oscillator for the WKT. * PLL allows CPU operation up to the maximum CPU rate without the need for a high-frequency crystal. May be run from the system oscillator, the external clock input CLKIN, or the internal RC oscillator. * Clock output function with divider that can reflect the crystal oscillator, the main clock, the IRC, or the watchdog oscillator. Power control: * Integrated PMU (Power Management Unit) to minimize power consumption. * Reduced power modes: Sleep mode, Deep-sleep mode, Power-down mode, and Deep power-down mode. * Power-On Reset (POR). * Brownout detect. * Unique device serial number for identification. * Single power supply. * Available as SO20 package, TSSOP20 package, TSSOP16, and DIP8 package.
